Something You Should Know - How to Actually Make Yourself Smarter & How Too Much Efficiency Makes You Less Efficient
Episode Date: March 14, 2019Everyone has heard about antioxidants. In fact, a lot of people take antioxidant supplements. But is more better? We begin this episode with a look at antioxidants, what they do and when too much of t...hem could be a bad thing. https://health.usnews.com/health-news/health-wellness/articles/2013/03/09/do-you-really-need-antioxidants Just how smart are you? Well, actually it depends. It is clear that your brain works better when you do certain lifestyle things and avoid other things. For example, how much you sleep you get and much alcohol you drink can have a real impact on how you think. David Bardsley, author of the book Smarter Next Year: The Revolutionary Science for a Smarter, Happier You (https://amzn.to/2tUXcK8) joins me to reveal simple lifestyle changes that can make you smarter and improve the way your brain functions at any age. What makes a woman beautiful? That may seem like a complicated question but in one significant way, the answer is quite simple. Listen as I explain. http://www.dailymail.co.uk/sciencetech/article-3477150/Bland-really-beautifulResearchers-simple-faces-likely-seen-attractive-easier-brain-process.html Efficiency is good but too much efficiency may not be. In fact, trying to be too efficient can actually make you less efficient. That’s according to Edward Tenner, a distinguished scholar at the Smithsonian’s Lemelson Center for the Study of Invention and Innovation and author of the book The Efficiency Paradox (https://amzn.to/2CaWgpk). Listen as he discusses how doing things efficiently isn’t necessarily always better - and how we have to balance efficiency with quality and intuition. This Week’s Sponsors -LinkedIn Jobs. For $50 off your first job posting, go to www.Linkedin.com/podcast -Calming Comfort Blanket.

Today on Something You Should Know...
If antioxidants are good, are more antioxidants better?
Uh, no.
Then, very practical ways to noticeably improve how well you think.
Starting with more sleep.
Adults need 7 to 9 hours sleep a night.
And I know all kinds of people, I'm sure you do as well, that say they get by just fine on five or six hours sleep.
That's what they're doing. They're getting by.
They are not performing at their cognitive best.
Plus, the surprising answer to the question, what makes a woman beautiful?
And are we too obsessed with efficiency today?
Probably so. The shortest way to say it is trying to be too efficient in the short run will make us less efficient in the long run.
Sometimes the pursuit of efficiency ignores some elements of quality that are hard to measure.
All this today on Something You Should Know.
As a listener to Something You Should Know, I can only assume that you are someone who likes to learn about new and interesting things and bring more knowledge to work for you in your everyday life.
I mean, that's kind of what Something You Should Know was all about.
And so I want to invite you to listen to another podcast called TED Talks Daily.
Now, you know about TED Talks, right? Many of the guests on Something You Should Know have done TED Talks.
Well, you see, TED Talks Daily is a podcast that brings you a new TED Talk
every weekday in less than 15 minutes.
Join host Elise Hu.
She goes beyond the headlines so you can hear about the big ideas shaping our future.
Learn about things like sustainable fashion, embracing your entrepreneurial
spirit, the future of robotics, and so much more.
Like I said, if you like this podcast, Something You Should Know,
I'm pretty sure you're going to like TED Talks Daily. And you get
TED Talks Daily wherever you get your podcasts.
Something You Should Know. Fascinating intel.
The world's top experts and practical advice you can use in your life. Today,
Something You Should Know with Mike Carruthers.
Hi, welcome. You know, almost every day I get an email from at least one person asking for information about something they heard in the podcast, either a book written by one of my guests or something else they heard.
They want to know what the source of that information is.
And while I'm happy to oblige, all of that information is in the show notes that accompany this episode wherever it is posted. And even if you can't find it for
some reason where it's posted, it's always on the website. The website has every episode in
reverse chronological order, the newest episode on top, and all of the information is listed right
there with the audio. And the website address is somethingyoushouldknow.net.
First up today, if you take antioxidants, that must be a good thing, right?
Not necessarily.
Some nutrition experts say that we're totally overdoing it in the antioxidant department.
Antioxidants are friendly molecules that go to work on evil free radicals.
And that's all good.
But as with anything, too much of a good thing can leave your body working too hard to process it all.
Flooding your body with antioxidants, especially in supplement form,
could do you more harm than good.
Now, antioxidants have been credited with helping to prevent all sorts of problems from aging, vision loss, cancer, heart disease, and stroke.
But how much they actually help is still up for debate.
Consumers gobble up products containing the buzzword antioxidant.
And the nutritional supplement industry really loves that.
But just remember that there is no evidence that they actually cure anything.
And the best way to get them is naturally in the food you eat.
And that is something you should know.
Who wouldn't want to be smarter?
Imagine if you could think better, make decisions better,
and just get through life with more brain power
to navigate all you have to do in a smarter, more thoughtful way.
Well, meet David Bardsley.
David became a dentist and oral surgeon after overcoming some serious learning disabilities when he was younger.
When he retired from surgery, he began researching and lecturing on the topic of cognitive performance. And he is the author of a book called Smarter Next Year,
The Revolutionary Science for a Smarter, Happier You.
Hey, David, welcome to Something You Should Know.
It's my pleasure, Mike.
So before we begin about making people better cognitively speaking,
if I do all the things you're about to tell me,
how much smart, I mean, how much is it worth the effort?
Are we just going to move the needle in the laboratory, or am I going to go, gee, I feel like my brain is really functioning better?
Well, that depends on where you are now.
If you're already doing these things, then doing them with a little more gusto
will move the needle a little bit. But if you're not already doing any of these things, then doing them with a little more gusto will move the needle a little bit. But if you're
not already doing any of these things, you can have a very, very significant increase in that
cognitive ability. And most people that I find that I know of are not doing these things or
they're not doing them to the degree that's necessary if you want that cognitive improvement.
When people hear conversations about cognitive ability and brain function,
I think there's a tendency to think, well, this only applies to older people,
to people as they're getting on in years and maybe their brain starts to decline.
Is this an older person problem?
The Center for Disease Control in the United States estimates that by age 40, 4-0, that 50% of the population start to show some signs of what's called mild cognitive impairment.
And mild cognitive impairment is, they're the first steps toward more severe cognitive impairment and ultimately, you know, with dementia and Alzheimer's. Now, not everyone, not everyone who has mild cognitive impairment by
any means will progress into more serious forms of dementia and Alzheimer's. But what we do know
is that 100% of the people with Alzheimer's and other forms of dementia started way back here
with mild cognitive
impairment. And that's why it's so important to either prevent it or deal with it at that very
early stage. So, but what does that mean, mild cognitive impairment? Does that mean I forgot
where I put my keys? Or does that mean I can't do math? Or what is my, give me an example of
mild cognitive impairment. You know, if you notice a song comes on and, oh, yeah, this is, oh, I recognize this song.
This is, oh, don't tell me I know who it is.
It's on the tip of my tongue.
And you find you just can't make that connection to that information.
It's a sign of cognitive impairment.
Or you might feel overwhelmed.
You know, perhaps someone is pressing
you to make a decision on something and you're not quite sure. And, you know, it just seems like
there are so many facts and information to try to make that decision and it just seems overwhelming
and you procrastinate. So you don't make decisions as quickly and you're not nearly as confident in those decisions.
Again, a lot of what you just described, we tend to associate with decline in brain function as you get older.
So if it's happening in younger and younger people, what's causing it?
Well, sleep deprivation is huge, absolutely huge.
We are a sleep-deprived nation. And adults, with rare
exception, need seven to nine hours sleep a night. And I know all kinds of people, I'm sure you do as
well, that say they get by just fine on five or six hours sleep. And they're absolutely correct.
That's what they're doing. They're getting by. They are not performing at their cognitive best.
One of the simplest things there is to do
in psychology is to test that cognitive decrease that occurs with sleep deprivation. If you have
just one night of disturbed sleep, you will have a measurable decrease in your cognitive ability
the next day. And the military have done the best studies I've ever seen. The military studies are
fantastic.
And they show that if you take a group of military personnel of mixed ages and you deprive them of sleep for, first of all, you give them a cognitive test.
And then you deprive them of sleep for 24 hours and then you retest them.
They will have a decrease of 30 percent in those test scores.
Now, most of us are never deprived of sleep for 24 hours straight, but those same military studies show if you take that same group of personnel of mixed ages,
you administer the cognitive test, and now you deprive them of sleep so that they get six or less hours sleep for five consecutive nights, and then you retest them, now they have a decrease of 60% in those test scores. It's one of the simplest things
that we can do to make sure that we're functioning at 100% of our cognitive ability is to get that
seven to nine hours sleep every night. Well, I think everybody can relate to that. I know I can
relate to that. If I don't get a good night's sleep, I know, I just know I don't perform as well the next day.
So what else?
What else besides getting more and better sleep?
One of the big factors is side effects of medication.
And not just over-the-counter medication, but prescription medications as well.
So many prescription medications have cognitive slowing as a side effect. And some of the,
you know, extremely, extremely common ones like statins, you know, drugs that are used to lower
blood cholesterol. And one out of four adult Americans, 25% of the adult population in the
United States takes a statin on a daily basis. A lot of anticoagulants, antidepressants have a negative
cognitive side effect to them. So, you know, our goal, everybody's goal should be to be medication
free. And that's, look, it's not possible for everybody, but for the majority of people,
it is possible. And if you can't be medication free, you want to at least be able to reduce that medication, you know, to a minimal level to get the desired effect. And that's so
many of the medications are due to our poor lifestyle choices. That's why we're on them
to begin with. Okay, what else? Well, you're not going to want to hear this. Most people don't.
Alcohol is not a friend of your brain and your cognitive ability. We can
grow human brain cells, human neurons in a petri dish in a lab and add just one little drop of
alcohol and instantaneously 100% of those brain cells will shrivel up and die. Now, we can't say
that that happens in the living brain because we have no means yet of putting a miniature
imaging device into a living brain so we can actually watch that interaction take place.
But you can drink a certain amount of alcohol and it will never get into your brain.
All the alcohol that you consume will first go to your liver and your liver has an enzyme which
breaks down the alcohol into two substrates A and, that get excreted in your urine.
If you present too much alcohol to your liver, then the liver doesn't have the capacity to break down that volume of alcohol.
Some of it will be broken down.
Some of it will pass through unchanged.
It gets into your bloodstream.
And in 30 seconds, it's crossed that blood-brain barrier and it's in your brain and you will feel the buzz.
So if you feel the buzz, you know that you've exceeded your liver's capacity to detoxify that alcohol and that alcohol has gotten into your brain and it's not doing you any favor, believe me. And let's face it, you know, people will often say,
oh, they love Gagasa wine because it tastes so good.
Most people drink because they want the buzz.
Yeah, yeah, I suppose they do.
David Bardsley is my guest.
He is author of a book called Smarter Next Year,
The Revolutionary Science for a Smarter, Happier You.
People who listen to Something You Should Know are curious about the world,
looking to hear new ideas and perspectives.
So I want to tell you about a podcast that is full of new ideas and perspectives,
and one I've started listening to called Intelligence Squared.
It's the podcast where great minds meet.
Listen in for some great talks on science, tech, politics, creativity, wellness, and a lot more.
A couple of recent examples, Mustafa Suleiman, the CEO of Microsoft AI,
discussing the future of technology. That's pretty cool.
And writer, podcaster, and filmmaker John Ronson
discussing the rise of conspiracies and culture wars.
Intelligence Squared is the kind of podcast that gets you thinking a little more openly
about the important conversations going on today.
Being curious, you're probably just the type of person Intelligence Squared is meant for.
Check out Intelligence Squared wherever you get your podcasts.
Hi, this is Rob Benedict.
And I am Richard Spate.
We were both on a little show you might know called Supernatural.
It had a pretty good run, 15 seasons, 327 episodes.
And though we have seen, of course, every episode many times,
we figured, hey, now that we're wrapped, let's watch it all again. And we can't do that alone.
So we're inviting the cast and crew that made the show along for the ride. We've got writers,
producers, composers, directors, and we'll of course have some actors on as well, including
some certain guys that played some certain pretty
iconic brothers. It was kind of a little bit of a left field choice in the best way possible.
The note from Kripke was, he's great, we love him, but we're looking for like a really intelligent
Duchovny type. With 15 seasons to explore, it's going to be the road trip of several lifetimes.
So please join us and subscribe to Supernatural then and now.
So David, because people like the buzz,
is there an acceptable level of drinking where it doesn't affect your brain?
Yes, there is.
And that depends on the individual.
So generally people who would have one drink a day and a drink is considered
you know like two ounces of hard liquor or six ounces of wine or one beer that that doesn't
have any negative effect whatsoever. In fact there are some studies that show that it actually has
has a positive effect but it's different you can't just take those exact numbers because it's different.
A 105-pound woman can't break down the same amount of alcohol as a 250-pound man.
So that 250-pound man can consume more alcohol without it ever getting to his brain
than a 105-pound woman can.
What else?
I'm going to imagine that stress has a lot to do with this.
Huge, absolutely huge.
Floods your body with two primary stress hormones, cortisol and adrenaline,
and they have a negative effect on your cognitive ability.
So anything you can do to reduce the amount of stress is good,
anything that you can do.
And I tell people if they have significant
stress or anxiety of depression, the best thing to do is to get some professional help.
Okay, what else?
Well, one of the very biggest ones is exercise. And I shouldn't say exercise, it's the lack of
exercise that leads to the cognitive impairment, the lack of movement.
So physical activity, vigorous physical activity is truly the rifle shot to improving your
cognitive ability.
There are now thousands of studies, not hundreds but thousands, I've read over 500 myself,
studies that show the improvement in cognition that occurs with vigorous physical activity. And it has to be
has to be vigorous. Unfortunately, a walk around the block with your dog isn't considered vigorous
physical activity. And that physical activity does two things. It stimulates the growth of new brain
cells, which we only discovered 20 years ago could occur. For 100 years before that, neuroscience taught that when a brain cell dies, that's it.
It's gone forever.
You don't grow new brain cells.
But 20 years ago, they discovered for the first time that, in fact, we can grow new brain cells.
And we can stimulate the growth of those new brain cells.
And the single best way of doing it is vigorous physical activity.
So if I vigorously run to the liquor store and...
And you vigorously run back. What else? Does diet matter much in terms of what you eat or
don't eat? And is it more what you eat or what you don't eat? You know, 30 years ago, it was fat.
Fat was the enemy. So anything you could do to lower the fat content of your diet
we thought was better and now the science showing that that's not true that it's really hyperglycemia
it's really high blood sugar that will have that negative effect because that sets up inflammation
the end products of the sugar metabolism will set up inflammation everywhere in your body
including your brain. And actually
now, and it produces this insulin resistance, and now in the science they're referring to Alzheimer's
really as type 3 diabetes. Your brain normally uses sugar as its primary sort of fuel, but if you
give your body so little sugar that there's not enough, then your body will selectively start
to use fats, which are known as ketones or ketone bodies, and it will start to metabolize those
fats. And a lot of people find their brain works much, much better if it uses these ketones or fat
as a fuel rather than sugar. So generally a healthy diet is what we consider, you know, lots of fruits and vegetables, not a lot of sugar, that kind of thing is a good brain diet as well.
Half of what you said I would agree with.
Lots of vegetables, not lots of fruits.
Fruits are very, very high in fructose, which is a simple sugar that raises your blood
sugar dramatically. Our grandparents and our great-grandparents didn't have access to fruit
365 days a year. They only had fruit when it was available in season.
Often in these discussions about mental decline and cognitive ability, particularly when it was available in season. Often in these discussions about mental decline and cognitive ability,
particularly when it comes to older people,
you hear the phrase, use it or lose it,
that older people need to exercise their brain by doing crossword puzzles
and other mental exercises that that will help.
What do you say? What's the science say?
Well, there have been a tremendous number of studies done, and they haven't, for the most
part, some have some show positive benefits, but most show that there's no significant increase if
you purposely stimulate your brain doing crossword puzzles or Sudoku or some of the commercially available ones
like luminosity and whatnot.
And so those things are absolutely not detrimental, and I would never discourage people from doing
those, but you don't want to hang your hat on that as being the salvation for your mental
acuity for the rest of your life because the studies show that they just don't make a significant difference overall. I wonder how much of this has to do with attention and intention.
In other words, if I put my keys down and go back and look for them later and I can't find them,
I don't know that that's necessarily a cognitive problem as much as it was an attention problem.
When I put the keys down, I probably wasn't paying attention to where I put them.
I wasn't real intentional about it.
So when I go look for my keys, I can't find them.
But the next time, when I'm careful where I put my keys,
the next time I know exactly where they are and I find them easily.
So I wonder if in this discussion about cognitive function
that a lot of cognitive function has to do with what you pay attention to.
Oh, that's a big part of it.
We tend to remember things that are important to us
and we tend not to remember things that aren't important.
So if you just walked in the house and you flipped your keys on the nearest table and
you start talking to someone, you may not remember where you left those keys.
It wasn't important.
You just flipped them somewhere.
But if you walked in and said, OK, I've got to be out of here in exactly 15 minutes, you
know, I'm going to put my keys right over here.
And you make a conscious effort.
I'm going to put them right here.
You'll probably remember where those keys are.
We remember things that are important to us. So because little, you know, because you misplace something, you know, I tell
people don't, you know, don't, don't get all bent out of shape over that. That's not critical at all.
And people will often say to me, well, you know, I have a terrible, I can't remember names. It's so,
it's so embarrassing, you know, and I'm worried about it. And I asked them, well, could you ever
remember names? Could you remember names 20 years ago or 30 years ago? And they say, no, I've been terrible
all my life at remembering names. Well, there's no change. So what we're looking for, it is a
change. If you were good at something and now you're not, you know, that's the change that
becomes worrisome. If you were never good at it in the first place and you're still no good at it,
then don't worry about it. There's been no significant decrease.
That's good to hear. I've never been good at math. I'm still not good at math,
but I've never been good at math, so I'm not going to worry about that.
I'm in the same boat as you, Mike. It's never been my forte.
So what's the big thing? And I think I know what you're going to say, but so what's the big thing?
If you want your brain to work better, what's the one thing you should do right now today to make it better?
If I had to say one single thing, it's physical movement, vigorous physical activity, and it has to be vigorous.
It's the only known thing that stimulates the growth of new brain cells, it stimulates the interconnection between existing
brain cells, and it increases and balances the what are called neurotransmitters, which are the
chemicals that let the electrical impulse travel from one brain cell to another. It does seem that
so much of the conversation about brain function and your cognitive ability is focused around people in their later years.
And yet, from what you're saying, it seems that if people paid attention to this and implemented this stuff earlier in life and in midlife, that it would go a long way to help prevent some of the problems rather than trying to fix problems that show up later in life.
David Bardsley has been my guest.
The name of his book is Smarter Next Year,
the Revolutionary Science for a Smarter, Happier You.
And you'll find a link to his book in the show notes.
Thank you, David.
Thanks for being here.
My pleasure indeed, Mike.
Thank you so much.
Since I host a podcast,
it's pretty common for me to be asked to recommend a podcast.
And I tell people, if you like something you should know, you're going to like The Jordan Harbinger Show.
Every episode is a conversation with a fascinating guest.
Of course, a lot of podcasts are conversations with guests, but Jordan does it better than most. Recently, he had a fascinating conversation with a British woman
who was recruited and radicalized by ISIS and went to prison for three years.
She now works to raise awareness on this issue.
It's a great conversation.
And he spoke with Dr. Sarah Hill about how taking birth control
not only prevents pregnancy, it can influence a woman's partner preferences, career choices,
and overall behavior due to the hormonal changes it causes.
Apple named The Jordan Harbinger Show one of the best podcasts a few years back,
and in a nutshell, the show is aimed at making you a better, more informed critical thinker.
Check out The Jordan Harbinger Show. There's so much for you in this podcast.
The Jordan Harbinger Show on Apple Podcasts, Spotify, or wherever you get your podcasts.
Do you love Disney?
Then you are going to love our hit podcast, Disney Countdown.
I'm Megan, the Magical Millennial.
And I'm the Dapper Danielle.
On every episode of our fun and family-friendly show,
we count down our top 10 lists of all things Disney.
There is nothing we don't cover.
We are famous for rabbit holes, Disney-themed games,
and fun facts you didn't know you needed,
but you definitely need in your life.

While it's hard to argue with the idea of being efficient and productive,
in some ways it doesn't seem like it's working very well.
We use all these systems and gadgets to be more efficient,
and then when we become more efficient,
it seems that the goal is to then become even more efficient. It's never enough.
And there seems to be this belief that efficiency equals better, that getting more done in less
time is always a good thing. Well, maybe, but really, efficiency just means quicker.
And maybe quicker isn't always better. Edward Tenner certainly believes that.
Edward is a distinguished scholar at the Smithsonian's Lemelson Center for the Study of Invention and Innovation,
and he has a long career as a teacher and a writer.
His latest book is called The Efficiency Paradox.
Welcome, Dr. Tenner.
Hi, Mike.
So, in a few words, what is the efficiency paradox?
The shortest way to say it is that trying to be too efficient in the short run will make us less efficient in the long run.
And why is that?
It's because real efficiency in the long run depends on all kinds of accidents and mistakes and learning from them in the short
run. And if we try to systematize everything, we get the feeling that everything is running
smoothly, but actually sometimes it's those uneven moments that eventually help us make a breakthrough.
So maybe some examples would help to explain the problem and also the solution here.
Yes, well, I think everybody's had the experience of taking a wrong turn somewhere
or taking another route and really discovering something in a city or in the countryside
that they didn't really realize that was there.
And very often those have led to some of the best opportunities.
I remember one occasion I got a call from John Kennedy Jr., who edited a magazine called
George, a political magazine that I would never have thought of contributing to.
And he had been in a bookstore in New York looking for another book,
and he saw my book, Why Things Bite Back, and he really liked it,
and he wanted me to write for the magazine, which I did.
Now it turns out that there are fewer and fewer bookstores in New York,
and maybe that one is not there now.
So you could say that it's more efficient to buy
your books online to see proposals for other books that would interest you because you had
been interested in a certain book. But a site like that, while it's efficient in giving you
more of what you've been interested in, is a little too efficient because it doesn't really
give you that kind of peripheral vision that says, hey, wait a minute, this is something kind of intriguing.
I want to look into that.
And so how are we pushed into being too efficient?
What are the things that are going on in the world that keep pushing us to do more in less time
and get it done and not look in our peripheral vision, but to stay focused straight ahead?
One of the big reasons is that efficiency is a movement.
By that I mean that people pursue efficiency on the assumption that pursuing efficiency is really going to make us more efficient.
Now that seems to be very reasonable. You want to do something, you want to set goals. But there is a paradox
there, and that is that we don't really have a lot of big data on big data. That is, we don't
necessarily know for sure how very efficient some of these things are. I'll give you one example.
Electronic medical records were supposed to be something that would relieve doctors of routine work,
would give them more time with patients, would eliminate errors,
and some of these things they may have done.
But what people didn't foresee is that in order to pursue this efficiency,
physicians and their staffs had to spend more and more time meticulously entering records into a
format that would be suitable for this electronic medical records. And now the medical journals
have articles about doctor burnout and how the cost of paperwork has really increased as a result
of this. So it's not so clear whether electronic medical records
as implemented so far have made us more efficient. Now, does that mean that I'm against electronic
medical records? No. But what I'm saying is that if we're not very careful, programs that are
designed to improve efficiency may really undermine it. And we can't assume that just
because something promises
efficiency that in practice it's going to deliver it. So how do you know? How do
you know if you're pushing the limits of efficiency or whether you're just being
smart and efficient? I think it's more a matter of balance. I think it's a
matter of using our intuition to counterbalance algorithms and vice versa.
We shouldn't necessarily depend on our intuition.
There are books that show how intuition has been very, very wrong.
But as I say in the book, there are other books that have warned against too much criticism of intuition, because very often intuition results from something that
we really know but can't articulate very well, and we have to learn how to listen to that.
So I understand, and I agree with you, and I'm all on board that maybe we need to use our
intuition a little more, maybe slow down, stop and smell the roses, that kind of thing.
But I also like the fact that I have all these things, mainly on my phone, that make me more efficient.
Yes, I do too, and I use them, but to give you one example, I use a GPS program called Waze, W-A-Z-E, which is now owned by Google.
And I started out as a critic of Waze.
I pointed out, for example, how Waze sometimes leads to cars taking routes through residential neighborhoods
and disturbing people and causing all kinds of complications. And I also pointed out that sometimes people using GPS are led down almost literally the garden path.
They can go onto boardwalks.
They can go onto railroad tracks.
In one case in England, there was a picture of a van that went down a narrow street,
and the street was so narrow that the van got wedged in toward the end.
So that problem has been happening.
But I discovered something else that ways, if you're not really conscious of where you are,
if you're just depending on this as a kind of autopilot,
will occasionally send you in the wrong direction. So once I was going south
on the Garden State Parkway in New Jersey, and Waze told me to go north. And I had to ask myself,
does Waze know of some kind of big traffic emergency and redirecting me, or is it more
likely that Waze is wrong? And I guess that Waze was probably wrong.
And I actually, later when I was in a safe spot, tried to see whether there was some problem that Waze had anticipated and was rerouting because it sometimes does that. But in this case,
it was just wrong. So every once in a while, it might be only one-tenth of one percent of the time,
a program like that can make a mistake.
But the problem is that that little mistake, very occasionally, can turn out to be a huge mistake.
So we can take advantage of the program, but we also have to recognize that all of these things have their hidden glitches,
and it's our intuition that helps us guard against them.
Yeah, well, with Waze, though, you don't know what you don't know.
If Waze tells you to go north when you think you should go south, well, you don't know, unless you went south, what Waze is rooting you around.
So I have found that when I disregard W ways, I usually regret it because they were
usually right. But there's no way of knowing every time whether it was right or wrong.
It does work. That's why I still use it. Most of the time, it does work. I'm just giving you
a few times when it was wrong. And I actually did disregard it the other day,
and I was sorry that I disregarded it.
So the problem can happen in either direction,
but there was another time when it told me to go on a certain route
and turn left, and a left turn there was both dangerous and illegal.
So what about the whole idea of efficiency as a concept?
Because I think, as I said at the beginning,
that people assume that being efficient is a good thing.
But because you're efficient doesn't necessarily mean you're better.
It just means you get it done faster,
but it doesn't mean that the quality is better,
that some things don't lend themselves to being efficient. Some
things take more time. Yes, that's another factor that sometimes the pursuit of
efficiency ignores some elements of quality that are hard to measure but
that contribute a lot to the enjoyment of life. So we can't really think of ourselves as flesh-and-blood robots that are designed to optimize things.
We really have to think about the other side of life, the ethical and aesthetic side of
life.
And so when the dust all settles, what's the advice? What's the trap we're
trying to avoid, or what is it we're trying to do that we're not doing? From your vantage point,
what's the advice? My advice, basically, is not to outsource life to algorithms. To be the user
of algorithms, yes, I think they're great, and I think that they can
really contribute a lot to the enjoyment of life. But there is an obsession in some corners of
Silicon Valley with doing everything as seamlessly and quickly as possible, and that, to me, cuts
into a lot of the serendipity that has been so important in long-term efficiency.
That is that so many of these discoveries come when people might be doing something wasteful.
People might be doing something that is not absolutely directly concerned with the future of the enterprise,
but that might in turn lead to something that makes the enterprise even
more efficient.
Well, in fact, there have been many cases of inventions where the inventor said, you
know, the idea came to him when he wasn't working on it.
He was doing something else, unrelated.
That's right.
Sticky notes are one of the most famous examples of that.
Sticky notes that were developed by a scientist at 3M, it was really
a kind of play or an accidental discovery. And it wasn't that 3M had a project to start a new
multi-billion dollar business. It was something that kind of came with free exploration.
Right, right. And I think that happens a lot.
And I like your example when we first started talking about how, you know,
sometimes you don't take the most efficient way to get there,
and you end up on a route that takes you somewhere that's beautiful and lovely,
and you're so glad you did it, but if your goal was to be efficient,
you would have completely missed it.
And that seems to apply to so much in life.
Yes.
In fact, I say for that reason that very often it's more efficient to do something in an
old analog way.
For example, psychologists have discovered that taking notes as opposed to using a keyboard device when you're listening to a
lecture will lead to better retention and understanding of the lecture. And the reason is
that the difficulty of summarizing what the lecturer is saying when you're taking the notes,
formulating the points, drawing arrows, or whatever you do, that effort in actively dealing with the material
is much more efficient in the long run than the supposed efficiency of capturing every word. When
you capture every word, it's what they call fluency. You think you have it all, but you
really don't have it all because you can't really necessarily
repeat it and summarize it in other words. And that's the real test of whether you learn
something, not whether you have all the words down there, but whether if somebody asks you to
put it in your own words, whether you understand it well enough to do it that way. And that is
much more real efficiency than just having everything down there as a text.
So I guess the question still remains, though, that how do you know which road to take at any given time?
Today, are we going to do things more efficiently or are today we're going to be a little more analog like slow things down because maybe that would be better?
How do you know what to do when? I'm not opposed at all
to doing new things, to experimenting with new technology, to being an early adopter, which I
don't happen to be, but I can understand the logic of that, and I think that's fine. But the danger,
I think, comes in thinking of these things not as something to experiment with and to understand and to use actively,
but as some kind of miracle that will offload your mental effort and will remove you from active engagement with whatever you're doing.
I think that's the danger.
Not the technology in itself.
I think it's great to play around with these things, and I often do,
but it's really the expectation that you bring to it.
Well, it almost seems like you really can't slow the train down,
that there's this movement of bigger, faster, better, quicker, efficient gadgets,
and it's really hard to jump off the train and say, well, let's go this way
instead. You're right that there is a momentum in society that leads to the adoption of some
technologies, and it can become very difficult to stay with the old one. There are some writers
who remain loyal to the typewriter, who feel they can work best with the typewriter, which is kind of amusing because when the typewriter came in, there were many, many criticisms of editors were insisting on typewritten versus handwritten copy.
And the reason was that they had so many different writers, so many different submissions, that it was getting to be impossible to read people's handwriting.
On the other hand, one of the interesting things has been that there is still a very vigorous market in pen and ink notebooks.
And you can go into just about any shop that sells stationery and see whole arrays of notebooks,
just because, as I was saying, there is something about capturing something in an analog form in writing that you can't get with a computer.
But some of the people, or most of the people who buy them, may have a variety of devices,
and they can use the devices for what they're good for, but they will use the notebooks for another mode of thinking.
So I think of that as a good metaphor for a larger trend. We need to reserve a space where we can exercise analog thinking,
where we can exercise our intuition.
On the other hand, though, technology does offer, often offers,
a better way to do things and to get things done,
and sometimes it is the better way.
Yes, and my point is not, again, not that we should reject these things,
but that we should use them critically and at a distance.
We should see them as tools, not as self-contained lifestyles.
Well, I like your message.
I like the fact that hearing this might make people stop and think,
you know, efficient isn't always better.
And maybe there's another way.

Thank you, Edward.
Thank you very much, Mike.
What makes a woman beautiful?
Well, it turns out simplicity is a big part of it. Simple is beautiful, according to a study from the University of Paris.
Researchers asked 156 men to rate 30 different female faces,
and the results clearly showed that men preferred simpler faces.
Why?
Apparently because the brain has an easier time processing simpler, plainer faces
than faces with distinguishing characteristics.
These findings do support the concept that first impressions are important,
and we do tend to subconsciously decide if someone is attractive or not before we consciously know it.
This may also explain why simple brand logos are more popular than complex ones.
For example, the Nike swoosh or the word Coke are simple images, so they're easier for us to process.
Same thing with an emoticon. It's simple.
The human brain prefers and is attracted to simple.
And that is something you should know.
