šŸ¤” Skepticism Towards Science and Scientists

The speaker begins by expressing their distrust in science and scientists, acknowledging the potential label of 'science denier' that may follow. They argue that there are valid reasons for this mistrust, citing the lack of merit in much of the foundational research in physics, which they liken to pseudoscience. The speaker also criticizes the reliance on mathematical models without empirical evidence, suggesting that this has led to the acceptance of unfounded theories in physics. They express concern that such issues in scientific methodology could extend to other fields, including climate science, and worry that this could undermine public trust in scientific findings.

05:04

šŸŒ Climate Science and the Issue of Trust

The speaker delves into the topic of climate science, admitting their initial skepticism about climate change due to observed issues in physics. However, after extensive research and engagement with the field, they conclude that climate change is real and human-induced. They discuss the problems within the scientific community, such as the lack of self-reflection on biases and the social reinforcement that can lead to overestimation of research importance. The speaker also addresses the unique challenges faced by climate scientists, including public scrutiny and fear of being misrepresented, which can introduce a bias towards downplaying the severity of climate change. They emphasize the importance of trusting data, mathematics, and logical arguments over the individuals presenting them.

10:06

šŸš€ Personal Project Launch and Community Building

In the final paragraph, the speaker shifts focus to their personal endeavors, introducing a new knowledge-sharing platform called 'quiz with it'. This platform allows users to create quizzes and courses linked to various types of content, fostering interaction and learning. The speaker highlights the platform's features, such as the ability to embed quizzes on websites or videos and monetize content, and mentions the existence of both free and premium features. They invite viewers to join the growing community and express excitement about this new venture.

Keywords

šŸ’”Science Denier

A 'science denier' is someone who rejects or doubts the validity of scientific findings, often due to a lack of trust in the scientific process or its practitioners. In the video, the speaker self-identifies as a 'science denier' in relation to the benefits of coffee but also uses the term to express skepticism towards certain areas of scientific research, particularly in the foundations of physics.

šŸ’”Pseudoscience

Pseudoscience refers to beliefs or practices that claim to be scientific but lack the empirical evidence and rigorous methodology characteristic of true science. The speaker argues that much of the research in the foundations of physics is 'pseudoscience,' as it involves theoretical constructs that are not grounded in observable phenomena, such as 'Multiverses' and 'invisible particles.'

šŸ’”Falsifiability

Falsifiability is a criterion of demarcation in science, introduced by philosopher Karl Popper, which states that a theory must be able to be proven false to be considered scientific. The speaker criticizes the common misconception in physics that if a theory is mathematically expressible and falsifiable, it is scientific, emphasizing the correct order should be that if it is scientific, it must be falsifiable.

šŸ’”Climate Change

Climate change is a long-term alteration in average weather patterns, particularly a rise in global temperatures, largely attributed to human activities. The speaker discusses the skepticism surrounding climate change and the potential for it to be perceived as a hoax due to the perceived pseudoscientific nature of some areas of physics. However, the speaker also emphasizes that climate change is real and likely worse than presented by climate scientists.

šŸ’”Statistical Methods

Statistical methods are mathematical techniques used to analyze and interpret data. The speaker mentions the development of better statistical methods, such as double-blind trials, as a result of recognizing pseudoscience in areas like ESP studies. These methods are crucial for ensuring the validity of scientific findings and are implied to be lacking in some areas of physics research.

šŸ’”Self-Interest

Self-interest refers to the motivation of individuals to pursue their own personal gain or advantage. The speaker suggests that the pursuit of self-interest, particularly financial stability, drives some scientists to inflate the relevance of their research, which can lead to a distortion of scientific findings and public trust.

šŸ’”Social Reinforcement

Social reinforcement is a psychological phenomenon where individuals conform to the prevailing beliefs or behaviors within their social group. The speaker describes how social reinforcement within the scientific community can lead scientists to overstate the importance of their research, contributing to a culture of exaggeration and bias.

šŸ’”Climate Models

Climate models are mathematical representations of the Earth's climate system used to predict future climate scenarios based on various factors and assumptions. The speaker acknowledges that while climate models have some problems, they tend to underestimate the pace of warming and the level of uncertainty, suggesting a potential bias towards underplaying the severity of climate change.

šŸ’”Alarmist

An 'alarmist' is someone who exaggerates a threat or danger, often to provoke action or reaction. The speaker discusses how climate scientists may be biased against being perceived as 'alarmist,' leading them to potentially downplay the severity of climate change in their research and public communication.

šŸ’”Trust

Trust in this context refers to the confidence in the reliability, truth, or ability of scientists and their findings. The speaker advises the audience to 'trust no one' and instead rely on data, mathematics, and logic, suggesting that trust in individuals or groups can be misplaced, whereas empirical evidence and sound reasoning are more dependable.

šŸ’”Data

Data refers to factual information collected through observation and experimentation. The speaker emphasizes the importance of trusting data in the scientific process, noting that in the physical sciences, including climate science, data is rarely wrong and is subject to scrutiny and correction.

play00:00

I donā€™t trust science and I donā€™t trustĀ  scientists. There, I said it. Yes,Ā Ā 

play00:05

itā€™s taken me some courage. Because after youā€™veĀ  watched this video some of you will call me aĀ Ā 

play00:11

science denier. And maybe youā€™re right,Ā  you know, maybe thatā€™s what Iā€™ve become.Ā Ā 

play00:17

I certainly deny any evidence against theĀ  benefits of coffee. Yes, make that triple.

play00:22

But seriously. I have good reasons to mistrustĀ  science, and scientists and so do you. I meanĀ Ā 

play00:28

look at this stock image of a scientist.Ā  Would you trust that guy? I wouldnā€™t.

play00:33

Yes, that means you shouldnā€™t trust me, either.Ā  And you shouldnā€™t trust climate scientists. No, IĀ Ā 

play00:39

donā€™t. And thatā€™s what I want to talk about today. Some of you have been following me sinceĀ Ā 

play00:45

approximately the Mesozoic Era, and youā€™llĀ  remember that Iā€™ve been highly critical ofĀ Ā 

play00:50

research in the foundations of physics. Iā€™veĀ  literally written an entire book about this,Ā Ā 

play00:56

back then when people stillĀ  read books, in the Mesocoic Era.Ā 

play01:00

Today we do 10 minutes YouTubeĀ  videos, so to make a long book short,Ā Ā 

play01:05

most of what physicists do in the foundationsĀ  is pseudoscience. Itā€™s paper production with noĀ Ā 

play01:12

scientific merit that teaches us nothing aboutĀ  nature. Itā€™s mathematical fiction, Multiverses,Ā Ā 

play01:18

tales about the origin of the universe, andĀ  invisible particles that no one ever finds.Ā 

play01:24

But that in and of itself is not theĀ  problem. Wait, Iā€™m serious, dammit!Ā 

play01:29

It happens every once in a while thatĀ  some research area drifts off intoĀ Ā 

play01:33

pseudoscience. For example, the early studiesĀ  on extra sensory perception, ESP for short,Ā Ā 

play01:39

thatā€™s telepathy, telekinesis and so on. ThatĀ  was once proper science. It was a phenomenonĀ Ā 

play01:45

worth investigating. I mean who hasnā€™t wishedĀ  they could use one or the other magical forceĀ Ā 

play01:51

of course scientists were on the case. But as time went on, it became clearĀ Ā 

play01:55

that there was nothing to find, andĀ  the people who were still working onĀ Ā 

play02:00

it were just pretending to doĀ  science with sloppy statistics.Ā 

play02:04

So, pseudoscience. PretendsĀ  to be science, but isnā€™t.

play02:08

This happens because scientists not onlyĀ  make mistakes, they sometimes make newĀ Ā 

play02:14

mistakes. If that happens, the scientificĀ  method itself needs to develop to demarkĀ Ā 

play02:20

the new mistake as pseudoscience.Ā  ESP studies for example led to theĀ Ā 

play02:25

development of better statisticalĀ  methods such as double-blind trials.

play02:29

The new mistake in physics was that physicistsĀ  came to believe that if you can write it inĀ Ā 

play02:35

maths and itā€™s falsifiable then itā€™s scientific.Ā  Unfortunately, itā€™s the other way round, if itā€™sĀ Ā 

play02:42

scientific then itā€™s falsifiable. Now if you makeĀ  that mistake then suddenly all kinds of nonsenseĀ Ā 

play02:48

ideas become ā€œscientificā€. And that in a nutshellĀ  is whatā€™s happened in the foundations of physics.

play02:54

But the problem isnā€™t that parts of physicsĀ  drifted off into pseudoscience per se,Ā Ā 

play02:59

because this happens every once in a while,Ā  in the natural evolution of the sciences. TheĀ Ā 

play03:04

problem is that it hasnā€™t had any consequences. Weā€™ve recognized the problem with ESP studies,Ā Ā 

play03:11

chucked them out of universities, andĀ  updated statistical methods to preventĀ Ā 

play03:16

that from happening again. But physicistsĀ  have been inventing unobservable things thatĀ Ā 

play03:21

no one ever finds for half a century and areĀ  still happily doing it, believing itā€™s properĀ Ā 

play03:27

science. And if it can happen in physics,Ā  it can happen in other disciplines, too.

play03:32

Thatā€™s why, after I finished writing my book inĀ  2016, I began to worry that climate change wasĀ Ā 

play03:39

indeed a hoax. I canā€™t blame people for lookingĀ  at the foundations of physics, concluding thatĀ Ā 

play03:45

much of it is obviously bullshit, and thenĀ  saying well see you canā€™t trust scientists,Ā Ā 

play03:51

theyā€™re just making up climate change.Ā  Because I worried about the exact same thing.

play03:57

I havenā€™t talked about this because Iā€™m afraidĀ  that this will just give some people anotherĀ Ā 

play04:02

justification to question science. But Iā€™veĀ  come to think that not talking about it justĀ Ā 

play04:08

makes it worse. It makes it lookĀ  like weā€™ve got something to hide.Ā 

play04:13

If you mistrust scientists youā€™re notĀ  alone. A recent study by members of theĀ Ā 

play04:18

Strategic Council of the US-AmericanĀ  National Academies of Sciences foundĀ Ā 

play04:22

that about 80 percent of those polled sayĀ  scientists are competent and trustworthy.Ā Ā 

play04:28

But the remaining 20 percent doubtĀ  scientistsā€™ motives. They doubt thatĀ Ā 

play04:33

scientists will stick with science when itĀ  goes against the scientistsā€™ self-interest,Ā Ā 

play04:38

like access to grants or other financial support.Ā  I think they have good reason for this doubt.

play04:44

Indeed the pursuit of self-interests,Ā  mostly financial stability, is whatā€™sĀ Ā 

play04:49

driving the problem in physics. Itā€™s baked intoĀ  the current organization of the research system.

play04:55

The vast majority of scientistsĀ  I know are not doing researchĀ Ā 

play04:59

to get rich. If youā€™re interested inĀ  money you do something else, like,Ā Ā 

play05:03

getting born rich. But still they need someĀ  income to pay rent and feed the kids, right?Ā 

play05:09

And this is why they have a strong incentiveĀ  to inflate the relevance of their research. ToĀ Ā 

play05:15

most of them this comes naturally, becauseĀ  theyā€™re excited about what theyā€™re doing.Ā 

play05:19

But the scientific community hasĀ  still no requirements whatsoeverĀ Ā 

play05:24

that scientists address their own biases. Thereā€™sĀ  no education no training no guidelines, nothing.Ā 

play05:32

That you expect scientists to generallyĀ  exaggerate the relevance of their researchĀ Ā 

play05:36

isnā€™t just a problem for the public perception,Ā  it feeds back into the community. You now haveĀ Ā 

play05:43

all these people telling each other constantlyĀ  that what they do is super important and theyĀ Ā 

play05:49

come to believe it. Itā€™s a classic exampleĀ  of whatā€™s called social reinforcement.

play05:54

Yes, same spirit that keeps flat eartherā€™sĀ  going. And is the same thing going on in climateĀ Ā 

play06:00

science? Of course. Does that mean that climateĀ  change is a hoax. No, itā€™s worse than that.

play06:08

Iā€™m not a climate scientist and IĀ  swear I have no aspirations to becomeĀ Ā 

play06:12

one. But Iā€™ve spent a lot of time trying toĀ  understand the basics, read lots of papers,Ā Ā 

play06:17

and textbooks and attended seminars andĀ  talked to climate scientists etc. Iā€™mĀ Ā 

play06:22

not asking you to trust me or anyone really.Ā  But I have found no major reason for concernĀ Ā 

play06:28

about climate science. Is the climateĀ  changing yes. Are we causing it yes.

play06:33

Every other option for what could be causingĀ  climate change, all the denier arguments thatĀ Ā 

play06:38

you have heard, have long been ruled out. Itā€™sĀ  the sun, weā€™re coming out of the little ice age,Ā Ā 

play06:44

cosmic rays, and so on. Itā€™s not like climateĀ  scientists ignored these possibilities,Ā Ā 

play06:50

the deniers are just repeating stuffĀ  that was laid to rest decades ago.

play06:55

Yes, climate models have some problems which Iā€™veĀ  talked about a few times before, but their biggestĀ Ā 

play07:01

problem seems to be that they underestimateĀ  the pace of warming and the uncertainty.

play07:07

And this returns me to the social problem.Ā  Iā€™ve found that climate scientists clearlyĀ Ā 

play07:13

*do have social problems in their community.Ā  But these problems present themselves totallyĀ Ā 

play07:20

differently than in the foundations of physics. In the foundations of physics, scientistsĀ Ā 

play07:24

basically seem to have concluded that theyĀ  donā€™t need to care about what the public thinks,Ā Ā 

play07:29

theyā€™ll get paid anyway, so nowĀ  they just ignore all criticism.

play07:34

Climate scientists in contrast, are afraid ofĀ  the public. Theyā€™re afraid of being hunted byĀ Ā 

play07:40

activists on either the left or right side, andĀ  of having their privacy being violated and ofĀ Ā 

play07:45

being quoted out of context. Theyā€™re afraidĀ  of being called alarmist. Theyā€™re afraid ofĀ Ā 

play07:51

being harassed by climate deniers. Theyā€™reĀ  afraid of being dragged into decades-longĀ Ā 

play07:56

lawsuits. Because these things haveĀ  happened and continue to happen.

play08:01

And honestly, I think that theyā€™reĀ  afraid isnā€™t entirely a bad thing.Ā Ā 

play08:05

Because it makes their argumentsĀ  much more careful and watertight.Ā 

play08:10

But it does create a problem: it introduces a biasĀ  in their arguments. Theyā€™re afraid of being calledĀ Ā 

play08:16

ā€œalarmistā€ and theyā€™re afraid of giving anyoneĀ  reason to dismiss their conclusion, and thatĀ Ā 

play08:21

creates incentives to make the situation lookĀ  less scary and to underestimate uncertainties.

play08:27

Basically itā€™s right that you shouldnā€™t trustĀ  climate scientists. But the conclusion fromĀ Ā 

play08:32

that isnā€™t what climate change deniers wantĀ  it to be. Itā€™s not that climate change is aĀ Ā 

play08:38

hoax. Itā€™s that itā€™s almost certainlyĀ  worse than the impression they raise.Ā 

play08:43

So whom can you trust? Trust no one. What you can trust for the mostĀ Ā 

play08:47

part is: data, maths, and logic. At least in the physical sciences,Ā Ā 

play08:52

and I count climate science as physics,Ā  itā€™s incredibly rare for data to be wrongĀ Ā 

play08:57

or fraudulent, and for that to remainĀ  undiscovered. It happens, but itā€™s rare.Ā 

play09:02

Itā€™s likewise rare that maths or statisticalĀ  analysis is just wrong, and for that not to beĀ Ā 

play09:07

criticised or corrected. Indeed, the problem inĀ  the foundations of physis is not that the dataĀ Ā 

play09:12

or maths is wrong, itā€™s that they have no data,Ā  and the maths isnā€™t about anything in particular.Ā 

play09:18

And finally, thereā€™s logic. Logic isĀ  your friend. Trust arguments, not people.Ā 

play09:24

This video doesn't have a sponsor because I wasĀ  afraid it might upset some people. But sinceĀ Ā 

play09:30

you're here already let me give you an update onĀ  my personal product launch, that's the simplestĀ Ā 

play09:37

knowledge sharing platform ever. I've calledĀ  it quiz with it and it lets you create quizzesĀ Ā 

play09:43

and courses and link them to any other content:Ā  news articles, blog posts, videos, what have you.Ā 

play09:49

You can embed them into your own websiteĀ  or newsletter or as a card on a videoĀ Ā 

play09:55

if you want to. You can monetize yourĀ  content and users can collect points fromĀ Ā 

play09:59

taking quizzes. The quiz creation is freeĀ  and will remain free, though we do have someĀ Ā 

play10:05

premium features because my software developersĀ  don't work for nothing if you see the problem.Ā 

play10:11

We now also have a comment feature and a smallĀ  but growing community. Iā€™m excited to be startingĀ Ā 

play10:18
