00:02 blinkist we all like to think we are

00:04 good at certain things above average in

00:06 certain areas most of us are at some

00:08 things but the truth is you are likely

00:11 wrong about how good or bad you are at

00:14 many things it is likely that you both

00:16 over and underestimate your actual

00:18 abilities in numerous areas of life and

00:21 the areas and the degree to which you're

00:23 wrong would probably surprise

00:26 you in a 1999 study psychologists David

00:29 Dunning and Justin Krueger discovered a

00:31 phenomenon that would be coined the

00:33 Dunning Krueger effect after giving

00:35 participants of the study various tests

00:37 that assess their abilities in humor

00:39 logical reasoning and grammar the

00:41 participants were then asked to self

00:42 assess their performance in relation to

00:44 their peers in the study Dunning and

00:46 Krueger found that people who perform

00:48 poorly on the tests tended to believe

00:50 that they did far better than they

00:51 actually did while those who performed

00:53 well tended to misperceive their

00:55 performance in relation to the average

00:57 of their peers in other words the study

01:00 would discover the cognitive bias where

01:02 people who are less knowledgeable or

01:03 experienced in an area tend to believe

01:05 that they are much more competent in

01:07 that area than they actually are and

01:09 those who are experienced and

01:11 knowledgeable in an area tend to

01:12 underestimate or doubt their abilities

01:15 these cognitive biases are the dun and

01:17 Krueger effect although the phenomenon

01:19 is debated amongst researchers and on

01:21 the surface the effect may seem

01:23 paradoxical and bizarre arguably the

01:26 cause is

01:28 understandable If someone knows knows

01:30 little about a subject or has little

01:31 experience in a particular area they do

01:33 not have enough experience or knowledge

01:35 to recognize the degree of their

01:37 incompetence in other words they don't

01:39 know enough to know what they do not

01:41 know if you're incompetent you can't

01:44 know you're incompetent the skills you

01:46 need to produce a right answer are

01:48 exactly the skills you need to recognize

01:49 what a right answer is said Dunning on

01:53 the flip side people with more knowledge

01:54 and experience in an area are aware of

01:56 the complexity vastness and difficulty

01:59 involved in being right or successful

02:01 and thus they are likely to be more

02:03 doubtful of their abilities they also

02:05 tend to think that others are more

02:06 capable in the area than what is

02:08 actually the case and so they are also

02:10 more likely to underestimate themselves

02:12 when ranked against others examples of

02:15 the dun and Krueger effect demonstrated

02:16 in studies include things like driving

02:18 where Studies have shown that 93% of

02:20 American drivers believe they are better

02:22 than average the phenomenon is also

02:24 often present in the workplace where

02:26 employees of companies tend to

02:28 overestimate their performance compared

02:29 to their co-workers where as many as

02:31 more than 40% of a company's employees

02:34 believe that they are in the top 5% of

02:36 performers of course everyone can't be

02:39 better than most there must be a

02:44 most throughout the processes of

02:46 learning strategizing evaluating and

02:48 reflecting there is another process at

02:50 play referred to as metacognition

02:53 metacognition is the awareness of One's

02:55 Own thought processes it's one's

02:57 thoughts about thinking a major part of

02:59 the learning process and a major factor

03:01 in being competent in something is the

03:03 ability through metacognition to

03:05 recognize patterns errors and problems

03:07 in one's thinking and then employ

03:09 strategies to deal with and overcome

03:11 them according to Dunning and Krueger

03:13 when someone is incompetent in an area

03:15 they lack metacognitive abilities in

03:17 that area as a result this lack of

03:20 awareness of their thought processes and

03:21 knowledge prevents them from recognizing

03:23 where and when they may go wrong and so

03:26 in their mind they never

03:28 do the phenomenon can be fairly

03:30 unsettling on the individual scale to

03:33 know that you don't know what you don't

03:34 know of course you already knew that but

03:37 the degree to which you're unaware in

03:39 the areas that you might have such

03:40 oversights where you might otherwise

03:42 feel pretty confident can be

03:44 disconcerting but it's even more

03:45 unsettling when considered on the

03:47 collective societal scale what's Curious

03:50 is that in many cases incompetence does

03:52 not leave people disoriented perplexed

03:55 or cautious instead the incompetent are

03:57 often blessed with an inappropriate

03:59 confidence booed by something that feels

04:01 to them like knowledge said Dunning

04:04 partly as a result of the Dunning

04:05 Krueger effect people who are not

04:07 qualified to speak on certain subjects

04:09 are still some of the most confident and

04:11 loudest who do more qualified

04:13 individuals rather tend to be less loud

04:15 and less simplistic and instead more

04:17 thoughtful and cautious and for

04:20 exceptionally high level experts since

04:22 they tend to misperceive how big of a

04:23 gap there is between them and the

04:25 average person it can be reasonably

04:27 assumed that they are likely to

04:28 insufficiently communicate about about

04:29 the subject they are an expert in with

04:31 the general audience and of course in

04:34 some cases complex things simply cannot

04:36 be fully explained quickly or in

04:38 comprehensive terms to individuals who

04:40 are not experts themselves and so out of

04:43 the lot here the incompetent but

04:45 confident amateure the competent but

04:47 cautious intermediate or the

04:48 exceptionally competent expert who is

04:50 confident but struggles to understand

04:52 and communicate with the Layman who is

04:54 more convincing to a mass audience of

04:56 individuals who do not know the

04:58 difference between correct and false

05:02 information it seemingly become more and

05:04 more common to have an opinion about

05:06 nearly everything maybe it's always been

05:08 this way maybe having access to all the

05:10 world's information but only enough time

05:12 to read the headlines and the incentive

05:14 to still leave a comment has exacerbated

05:16 this human tendency whatever the case

05:19 because of this and in combination with

05:21 the dun and Krueger effect some of the

05:22 voices we hear the most of are the least

05:24 qualified useful or accurate they are

05:28 rather voices of confidence and Charisma

05:30 not nuance and Care the right voices

05:34 rather are often quieter harder to parse

05:36 or still looking for the right words and

05:38 means to express themselves it's natural

05:41 to want to have a voice that is heard

05:43 it's desirable to be perceived liked

05:45 followed impactful being a voice of

05:48 change and impact is a noble goal but

05:51 sometimes the greatest impact is silence

05:54 does the world really need more voices

05:57 or does the world need more careful

05:58 voices

06:00 of course the irony here being a voice

06:02 that is not silent is not lost but the

06:05 point here is not merely about being

06:06 silent outright it is about being

06:08 carefully noisy at least attempting to

06:11 be it's impossible to have no opinions

06:14 but it is possible to have less or be

06:16 more careful around how we hold the ones

06:18 we

06:20 do once you know about the dun and

06:22 Krueger effect it might feel like now

06:24 you are no longer susceptible to it or

06:26 perhaps you might feel as though it's

06:28 something you never were susceptible to

06:30 you're not the kind of person who

06:31 overestimates their abilities you're

06:33 cautious and thoughtful and self-aware

06:35 you never make claims about things you

06:36 don't know you know your blind spots but

06:39 of course that's not how blind spots

06:41 work in truth do you think anyone who is

06:44 subject to the dun and Krueger effect

06:46 overestimating their abilities or

06:47 knowledge thinks they are the phenomenon

06:50 is precisely that one does not know that

06:52 they are a victim to it the first rule

06:55 of the dun and Krueger club is that you

06:56 don't know you're a member of the dun

06:58 and Krueger club said Dunning in fact

07:01 thinking you're impervious to the

07:03 Dunning Krueger effect is itself an

07:05 example of the Dunning Krueger effect

07:07 you know just enough about the

07:08 phenomenon to believe you can circumvent

07:10 it while not knowing enough to know you

07:12 probably can't at least not

07:14 automatically or

07:16 universally perhaps however we can

07:18 overcome it more often with a certain

07:20 kind of awareness and attitude by more

07:23 regularly being silent by being willing

07:25 to be a nobody to let our voice our

07:28 presence our existence

07:30 not always be involved we can perhaps be

07:32 a victim of the effect less and be on

07:34 the right side of the effect more in

07:37 truth the average person is well read

07:39 and experienced in a relatively small

07:41 quantity of things at best we don't need

07:43 to be in more than that we shouldn't try

07:46 or pretend to be after a certain point

07:48 the quantity of opinions one holds is

07:50 almost always inversely proportional to

07:52 the quality and accuracy of them we will

07:56 inevitably often fail at correctly

07:57 making the distinction for ourselves and

07:59 knowing which areas we belong in and

08:01 which of our opinions deserve sharing

08:04 but that's okay the goal here is simply

08:06 to try our best ultimately the Dunning

08:09 Krueger effect is a continual sliding

08:10 scale that follows us through life as

08:12 long as we take on new Endeavors new

08:14 challenges new goals we will be

08:16 incompetent in certain areas and as long

08:19 as we are incompetent we'll be partially

08:21 ignorant to the true degree of our

08:23 incompetence but as long as we continue

08:25 to learn and grow we will also uncover

08:28 new knowledge and we will continue to

08:29 realign our self-perception with our

08:31 actual abilities life is a continuous

08:34 cycle of realizing how little you knew

08:36 how much you were wrong and how complex

08:38 things really are and then realizing it

08:51 blinkist our awareness of oursel is

08:53 limited distorted and often confusing

08:56 our biases and oversights have tangible

08:58 impact on our lives

09:00 they disconnect us from reality and

09:01 paint our decisions in colors we are

09:03 partly blind to the books Thinking Fast

09:15 Powerful insights into the nature of how

09:16 we think how we can often misunderstand

09:19 our thoughts and feelings how we can

09:20 become misaligned from truth and how we

09:23 can gain back better control of our

09:24 thought processes and make better
