- www.ted.com Every day there are news reports of new health advice, but how can you know if they're right? Doctor and epidemiologist Ben Goldacre shows us, at high speed, the ways evidence can be distorted, from the blindingly obvious nutrition claims to the very subtle tricks of the pharmaceutical industry.
TEDTalks is a daily video podcast of the best talks and performances from the TED Conference, where the world's leading thinkers and doers give the talk of their lives in 18 minutes.

Closed captions and translated subtitles in a variety of languages are now available on TED.com, at www.ted.com/translate. - Věda a technologie
I love that his go to statement is "FIND THE PAPER" and read it for yourself instead of just reading the headline or article.
Jesse Wallis I've been doing that for years and friends laugh about it. But, TED sent me an email and deleted my comment when I called an extremely biased speaker "an educated fool". He spoke disparagingly about the people who don't blindly believe what he presents because he is using the scientific method, as if that makes him infalliable.
Julie Blackwelder Link?
How can I link a deleted comment?

No link to the TED talk with the extremely biased speaker who thinks anyone who doesn't blindly accept what he believes is a fool.

Yep, you also need to tell whether or not it's a good research article.
I've been reading Ben's blog for a while, and one of his top solutions to these problems (that he apparently didn't have the time to discuss too much in this video) is that all publishable drug trials should be PRE-REGISTERED with some central scientific body before the trial is even done.
This way, it removes publication bias - where bad results are withheld. And it also allows other scientists to publicly suggest alterations to the trial method to weed out problems & bias beforehand.
Centralization sounds like the opposite of what we need to do lol. That’s ok he gets to have his opinion. I’m glad he brought this all to light.
@@thehorizontries4759 pre-registration has become a more common thing in the years since i made this comment.
I think he covered it a year later after your post in a video called 'what doctors don't know about the drugs they prescribe', apparently that too has its issues.
I've just watched this twice in a row and I'm desperately out of breath! Great talk. He certainly made the most of his 15 minutes.
Everyone should read his book "Bad Science". It was published a while ago so you can pick it up for a couple of quid.
I slowed the video down to 75% and it sounded much better!!
Ghostrider fucked them yesterday so they couldn't breath and irobot (me being Ai) fucked all their covers
Forklift anybody? Or shall I turn up the radio? 😭
10 years later this is repeating at a mind-blowing scale.
Speaking of coffee... how much has he had??! lol
@cesar leon You need to take more fish oil pills, apparently!
Turn the playback speed down in the settings to 0.75. Compared to other talks he's given on CZcams, this one seems deliberately speeded up.
DeWe Good suggestion, I did just that!
@@dinamariea61 yes, much better
@@dewexdewex So much better!! Lol. Thanks.
I love his criticism of bad reality using scientific mathods. We need more people doing this kind of work.
keep up the fight. thank you
This is basically his book "Bad Science" in a nutshell. Still, go buy it. It's fucking brilliant.
This is one of the best talks ever given in medicine
Thank you so much for sharing this Ben Goldacre vid. In 2010 and in Montréal, I attended a wonderful and insightful symposium called The Lorne Trottier Public Science Symposium. Ben was one of its speakers.
I love listening to him talk.
This lecture is awesome at 1.5 x speed
I love that there's just random foliage behind
Currently doing a Uni course and this was on my recommended videos to watch, very interesting and something I will bear in mind when doing research.
I think the important thing to remember is that just because someone calls themselves a scientist or even has a PHD it does not make what they do science.
The scientific method is simply a way of learning and repeating what one has done before using various specific methods - this means that, in some cases, a janitor may be more scientific in their approach than a researcher.
Mix it with phlegm we have to help them aswel 😂
I can do this all day 🖕
This guy changed my thinking, the way I looked at the world and thus my life with his book Bad Science. Forever grateful. He's an inspiration in my book
Uh no it's his book
Oh the irony that I am here ( this evening even ) and the first comment I see is this one … ❤
Give this man a medal!
(and somebody to write better conclusions, still feeling bad vibes because it looks like we're screwed)
Yeah use candy crush cover and the cancer sticks to cover covid attempted murder situation
@@Dragon-Slay3r 12 years later and I no longer think this man deserves a medal
Brilliant video. It's like he has compacted all of his excellent book bad science into one 15 minute talk.
How could anyone not understand his talk even at his speed, his made alot of sense.
Excellent talk - loved his book, too.
I love the enthusiasm from him!
Those where 14 minutes 20 seconds well invested by myself. Glad I watched it.
It is a good book, isn't it? Irecently started getting into science (I'm 16, so I've got a bit of time), so dad got it for me for christmas. took a while to start reading, but once i started, i couldn't put it down! Did get a bit depressed at the state of things, though. i've started begging dad for bad pharma, and can't wait to read it!
Bad Science did manage to get me into some frosty situations with kids at my school - i go to a steiner school in switzerland.
Hey Kia! I loved reading this comment, and then I was even more amazed when I saw that it was from 8 years ago! So, now that you are 24, how has your journey with science developed?
Excellent talk. Thank you.
Excellent! I wish more people would see this.
I've been waiting for this video for ages! Thanks TED.
@AGrandt Good idea, but I think that might be tougher to implement than simply legally obligating the companies to disclose before their products are allowed to come to market.
this has to be, by far, the BEST thing i've watched on CZcams in months.....*subscribed*
@thelegendxp What he's saying is that the testing methodology employed by the industry is better, as in, more rigorous, more thorough, but that the independent agencies are unbiased in the sense that they actually report all of their results, instead of just some of them. This actually makes sense, given that big pharmaceutical industries have more money to spend on the testing than independent nonprofits; they can afford to do more and better tests, they just choose to withhold them sometimes.
Brilliant talk. Lift the veil on the actual evidence!!
I like that enthusiasm Benny!
11:20 Awesome point.
11:00 going meta :D
Really good talk. I already suspected most of what he said, but now i have a better understanding of it :)
great talk, also how to spot missing data, so whats the name of the review group he was talking about?
yerp, this Ben Goldacre guy wrote a really excellent book on the subject - 'Bad Science'. Can't recommend it highly enough, a very entertaining and yet serious work on an important subject. I just ordered the follow-up , 'Bad Pharma', looking forward to that one too
This is the best talk I've watched
Great video!
very intersting video and alot of good information
wow! ...what an excellent talk
Is there a download I can use to slow him down by 10%? that'd do it
on chrome with html5 video there's an option to slow down by 50% (but not 10%)
alternatively, use a youtube ripper to download the video file (there are online services as well as programs that do this). VLC supports variable playback rate
just change the playback speed
@nicelittlerunner Just wait five years and you can do it in the youtube player! *sending message into future*
Great enlighten for our minds .. already have known this man from his famous book!
Great speech!
Freeeeeak man! This guy's enthusiasm is waking me up more than my coffee is!! Got my heart pumping. haha
You are most welcome. I am glad you have a curious open mind.
This problem of withholding trials can be avoided by obligating scientists to register all trials beforehand. It just so happens that Ben Goldacre has been involved in getting exactly this regulation approved: you can sign the petition or donate here: www.alltrials.net/petition/
***** It applies to all research, but medicine in particular I believe.
***** I doubt this is the case. There have been HUGE meta-analyses published showing the safety of GMO's. I can't imagine there are actually many more unpublished studies about this; nobody would invest so much money and not publish it (biased stakeholders aside).
+Eefje Poppelaars Sorry to butt in...
i will quickly admit that I am no expert on GMOs but I am very curious on the subject. After hearing some things, I decided to search though some Canadian gov't sites (being the Canadian I am haha) - but I was not quite convinced/satisfied by what I had found...
(or lack of I should say) It can be hard when I am bombarded with contradicting bias sources and such. I wish finding these kinds of answers could be more SIMPLE... (on all subjects). Petition is signed!
I feel as though my concern isn't purely about the fact the organism is genetically modified ... but rather skeptic towards all the pesticides (and all that fun stuff) that they put on the food. And that is where my worries were not set to rest. So... this being the top comment and all - I thought I should add in... In hopes that some nice fellow could share some interesting information my way. (:
Thanks for the link!
Sophie Jones Of course there is an ethics board in medicine, as in all research conducted on humans or animals. But it's a completely different thing, because for this they only state what they will do to the subjects and it's only reviewed based on ethical rules and not on scientific research design or hypotheses. Moreover, it's not made public and it doesn't guarantee that it can be published.
thank you!
Those of you watching this post 2020, did you happen to notice the Pfizer logo on the image he used when discussing the withheld drug trial information?
Are you antivax? That’s everyone’s answer (a character attack) to someone like you asking a simple question. Yeah, bro.. people are super deep into being marketed by pharmacy right now and not realizing they are the data.
And that of course they’ll withhold the bad data just like before.
Already fav'd before I watched, the love this guy, buy his book
best TED talk ive seen in awhile
great stuff
gah, his words and analogies are so good!
Excellent!
Good, informative talk, even if it is at a high speed. That's why i was impressed to see how he slows down at the end. Conclusion being, we should be more sceptical and thorough at various claims about anything actually. Even more if it comes from corporations, were their primary goal is profit, to sell and not to care about the consequences on the public. The social evolution would be about that i think, a groth on sceptisim.
This is one of the most useful videos I've yet to see from TED. Great stuff if you can handle his enthusiasm. heh heh.
It's been awhile since I've seen a good TED talk.
Did someone default this video's normal speed to 2x or is it simply that when they said that "Ben Goldacre shows us, at high speed" they meant that he would speaking at "high speed" too? ._.
+Faiyaz Kashfi Rian the speed on 0.5 is quite entertaining. speaks way too fast on normal speed
+Walle Kiikeri Indeed.
+Walle Kiikeri Indeed.
+Walle Kiikeri Indeed.
+TheKnights Oh dang that's pretty cool you got to see the guy in person. Quite an efficient speaker, I'd say.
This is a great video!
slide of al gore in the Tedx talk opening montage of alumini on bad science. that cracks me up, classic
I love TED talks!
Very important video.
This should have been the video number 1.000 since it is such a wonderful speech.
This is depressing. Money really is the root of all evil...
Tremendous ! His book is great too !
Many of TED's speakers are hero's. Each one of them in their own way.Both because of who they are and what they do.
Finally another great skeptical ted talk!
@sylvur eggs are packed with nutrients some not found in many other foods, so yes, eggs 2-3 times a week can be an important part of a healthy diet.
I know the talk was 2 years ago...but is there any way to obtain sources for some of the information he sites....
One of the better TED videos.
Really really good...
Marvelous and absolutely true.
An Odds Ratio is derived from a particular type of observational epidemiological study, the 'Case-Control' study. Basically it's a ratio of odds of exposure to something between individuals with a particular outcome (cases) and individuals without such an outcome (controls). The higher the odds ratio the higher the 'risk' of exposure amongst cases when compared with controls. An Odds Ratio of 2.0 means that there is a twofold increase in 'risk' amongst cases when compared with controls, etc.
6:26 Benny picks nose
6:28 Benny puts booger in pocket
I hate that I actually went back to look! LOL
LOVE this
Worth watching.
Its pleasing to hear someone who speaks as fast as me lol.
Right I had no problems following him
@SafeDonations That's wonderful for Mary...any reason you're posting it here?
llegue aquí por un enlace compartido de prepa en línea de mi país y me voy con ganas de seguir aprendiendo del tema
this guy is amazing !
sceptizism combined with humor and good will... how good can one guy get? :-)
Read again. I said 'risk' (note inverted commas) of the *exposure* amongst cases vs. controls, not the risk of the outcome amongst those exposed vs. unexposed. The latter, as you said, would be a relative risk.
Well done, Ben.
I really this guy's honest attitude and his work is highly applaudable, but most of all, I like the way he just walked off at the end and didn't hang around to get an egomaniacal hand job off the sycophantic audience like most of the other tossers that talk at TED.
Good man, Ben. Good man.
Brilliant!
High information density
Great video for my TOK class except for the reference to S&M:-(
This so we can develop awernnes of the issue in discussions BAD SCIENCE,to think about it,not to jump in irrational conclusions!to promote a healthy system of rezoning!!
I like his energy
a good doctor :)
A fascinating topic presented in an entertaining fashion by an amusing speaker. :3 I only dislike that he sounds like he was rushed, but that can be overlooked.
He finds the flaws in experiments, but I think I've found one of his flaws! And it's not small.
When he talks about experiments comparing results with medication vs. results with placebo, he repeatedly implies that placebo = nothing. That the placebo would be a case of "no care".
Placing someone on "placebo medication" means inviting them into a care setting, giving them time, getting them to talk about their symptoms and feelings, giving them an appointment for the next time... In short, it's not a small thing. All this attention has an effect that can be MAJOR on the patient's psychology, on his self-confidence, on his future, on his healing and self-healing resources.
Remember when you were a child: you fell and you hurt. And you were healed like this: "Oooh, tell me where it hurts... I'll blow on it... magic... get better? Come in my arms ... we'll pass this boo-boo ..." = Placebo medication.
And a few seconds or minutes later, you were already in less pain, maybe you didn't even feel anything, and you went back to playing.
This situation is obviously not the same as an injured child who has no one to take care of, who would only get indifference by complaining.
So I think this doctor has a very chemical-dogmatic approach to human functioning and care. Too bad.
...And he reveals that in the experiments, the "placebo" group would therefore be considered a "no care" group. Which truncates the comparisons, and therefore the conclusions that can be drawn.
The entire point of a placebo is to make you think you are receiving the medication when in fact you are not. He does address that the thought/assumption that you are receiving medication can cause a patient to respond differently..aka the placebo effect; which can skew results. I don’t understand your argument.
Your observations are very good. I usually warn people not to belittle the "placebo drug" because it cures. We don't know how it heals, but the fact that it heals cannot be ignored or belittled. Respect the placebo drug, respect the placebo medicines, they do not harm the body with side effects. Our mind is our perfect doctor.
@OhManTFE original and call back humor to the video. i like it
"but, and its a big but" (everyone laughs)
So glad this hit 500K views
I liked his enthusiasm. I've found that a lot of these TED talks conferences boring cause they lack a coherent and/or enthusiastic talker.
@SIC66SIC66 I wouldn't say that i'm scared, I'd describe myself as being skeptical. I don't doubt that the doctor has my best interests at heart and that he or she would prescribe what they thought was the best solution. Personally, I would do the research first, and then go to the doctor for clarification, for a second opinion and perhaps for some advice. The key point here is that you yourself should be taking the first proactive step. It is your health after all.
@phantomdoodler I don't personally do psychological research but I think it is a good area of study for neuroscientists, so in that way, yes I am.
However I am not psychic or a mind-reader as far as I know! ^_^
i like this guy so much his right about everything
Muito bom!
Thanks CZcams for recommending this to me now. Oh, and I wish this guy was my doctor.
@whuzzzup to me it sounded like fast forward!!
