    We all need to hear this!!! This is exactly what I’m trying to do introspectively and something I want to talk about. We need more humility in our world. I’m willing to get it wrong. I have many times, but I can’t fall for the lie that WE, our humanity, is doomed. I see examples of humility and vulnerability and personal emotional bravery. I work on these things and explore the grey between the clear black and white posts of all the things.

    Thank you for your kind response, glad you found it to hold some truth. Like Voltaire used to say: 'Ecrassez l'infâme' - smite the indecent. Strife for truth, no matter what. Stranding halfway there and coming up short is far from shameful when a goal is as unachievable as it is sublime.

    I don't know what schools he went to but my schools were always clear that you could only be right or wrong on questions which were of that nature. The grade was otherwise founded upon the depth of the discussion to the problem, how much insight is displayed and how plausible the conclusion or solution is.

    This makes alot of sense, and I love how Archie Cochran made his point to the room full of doctors! It really illustrates that their system has a vested interest in maintaining the status quo even when they're proven wrong and new data proves old assumptions outdated. Throughout history almost every famous landmark in medicine was made by a person who was persecuted by the peers of his/her era, and then later was recognized as a great medical achievement and accepted by the mainstream. Some of us patients are trying to change the status quo in medicine and change it back to where doctors' first responsability is to their patients and rather than letting a patient just suffer to try things to help them. If they wait for Placebo controlled clinical trials to act on behalf of their patients many will die waiting for these empirical treatments to be accepted by mainstream medicine and be considered "standard practice".

    This video shows me again how important it is to leave ones comfortzone and try things. Plus: I don't feel bad about failing anymore as long as I'm aware of the mistakes done and I admit that even though I'm a self-critical person, it's hard to see that I could have been part of the problem... especially in LOL, still a huge thx to gbay99 for giving the comunity something to think about.

    A wonderful and insightful talk by Tim, it certainly has inspired me to be more aware of the differences we all carry around with us.
    My task now is to see how I can translate that into my service that I provide for people in every corner of the planet, there has to be ways of reaching out to more people than I am at present.
    Again thank you for stimulating my thoughts around offering something that fits more people.

    One of the main points I struggle with when thinking of supporting trial and error, and the scientific method in general, is the cost involved in a fully scientific world. The one thing that can be said for the god complex is its low cost both financially and energetically.

    And I couldn't help but think about Ron Paul when Tim described a politician saying he didn't know all the answers, but it would be good to try different things!

    we did trial and error at school in maths. like x^3 + x = 10 work out x (i think it was like that) you estimate then move up or down until you have an answer between two approximate points and eventually narrow it down. It worked in the same way as if i say I have picked a number between 1 and 1000 you ask if its above 500. I say yes. You say is it above 750 i say no etc. My point is trial an error is taught.

  • @DSBrekus
    @DSBrekus 12 років тому

    @NevilleRhysBarnes I can see that my comment was a bit jumbled so I'll try to clarify. Yes artists do try random things and what sells sells, so you can see some of the trial and error/evolution in art. But the reason they try random things is 1. there's no societal risk for failure and 2. they are simply driven to express themselves in some odd form and have intuition that it will be good. Also, art IS subjective, tastes change over time so there will never be a "right" kind of art.

  • @LIANG14
    @LIANG14 13 років тому

    @guitarplayer1293 I can see your point, however you have to remember that evolution didn't have a sentient being that could pick out the 'best' evolution, unlike us where we can (like he described with the nozzle) find the best within a few months.
    I think encouraging mistakes is the best way, it'd make students feel more confident and willing to question their actions. As long as you also teach them to query their mistakes.

  • @CJ700777
    @CJ700777 13 років тому

    @shakyl008 I'm not sure either but it might have been a reference to the trial and error bit he was pushing. So by making mistakes in the "right direction" one is using selective pressure and moving toward positive results in the future.

    Yes it is, that's why talks like these are needed. People need to realize that making mistakes isn't bad if you eventually get something better.
    In fact, several companies are already using a trial and error system to get results. Look at Google for instance; they throw loads of things at the wall and expand on what sticks. Nobody can deny the results.

    The problem with trial and error in use of public policy is that mistakes could potentially be so desvastating on such a large level that experimentation becomes an impossible practice, and that many effects may not be felt for years that indicate whether or not the policy was a success. Human beings and societies are not infinite subjects to fiddle about with; entire generations could pass on before the right way is hit on.

    However, the kind of T&E he seems to talk about is more of the genetic kind, selection and variation. And with the nozzle example, "we have no idea how or why it works". As with the scientific method those two questions are the questions we try to answer.

    Not everyone is ready or willing to entertain the thought of change. Ideas that require deep introspection of our own belief structures seem to be the most painful.

    @derek24hudson Correction: "close minded" people use exactly the same tactics. As a Christian I absolutely LOVED this as well as many other TED talks. The God complex is easy to get sucked into. You reach a certain level of understanding on something and decide that is enough and you don't need anymore information. It happens to religious people and atheists alike. It is part of the human condition. The moment you close down to new information (no matter the source) you have the God complex.

    When discussing a resource based economy, many people get hung up on the question "who makes the decisions?" A far more relevant and important question is "How are decisions arrived at?" Using the tools of methods of science in application to human concern, we can have access abundance for all people and significantly decrease crime, hunger, poverty and war. To learn more, please look into the Venus Project and the Zeitgeist Movement.

  • @johnybravo5089
    @johnybravo5089 5 років тому

    Tim Harford has given a very insightful lecture on a very obvious though vitally important concept of trial and error. He makes a solid point that business organizations, politicians, etc. should incorporate trial and error into their decision making process. But this concept works only for engineering or technological development. When human resource is involved, this doesn't really work. If you do too much trial and errors, your organization will become slightly unstable and the employees might become frustrated. Even in the case of national development, it is extremely improbable to succeed in your first attempt. Let us just take the case of demonetization in India. In his manifesto in the 2014 elections, the Prime Minister had promised people to reduce the black money in the economy. This was a big promise and wiping out black money is considered extremely difficult, if not impossible. He made his first trial attempt by demonetizing the currency notes and replacing it new ones in the hope that black money will be rendered useless. This can be said to be an experiment, a good one, because it FAILED. He recieved a huge backfire from opposition parties and the citizens, to the extent that it might cost him his chair in the next elections.
    There are dozens, or even hundreds of experiments for his goal out there, and there is one out there which might work. But can he do even one more experiment?

    @Lightrider4444 Not everyone is motivated by money. Many are motivated by power. Some aren't motivated at all. But the point is, once a group of people start to use something as money (ie, "I'll trade you this for that" type of thing) then you start to put a demand on some items, giving them a monetary value. Now that things start to have a value to them, you get people that start to collect and hoard those items, creating a short supply, increasing the value, making the holder wealthier.

    @qtutoringhelps What he does conclude in his talk is that the government should try many different things. They are trying charter schools in some states, some will fail, some will work, and from that we can see what works best. This isn't an excuse to privatize everything, it's merely an excuse try as many options as you can.
    Banks fund businesses regardless of whether they fail. Where does the failing 10% get their money? Every experiment is an investment toward the best solution.

    13:52 "It's so hard to admit our own infallibility" - He means fallibility.
    He has a point, but it is not an across the board point. Much of the world is complex, but not everything is. His point about trial and error should be applied in areas of complexity, but binary issues still exist. 2+2 still equals 4. Wisdom is knowing where to apply what, and not arguing for universal uncertainty - otherwise our future generations will keep reinventing the wheel.

    @BitterBurst It's being done. There is a league table of countries which uses a range of social factors to rank countries.

Depends on how you want to live. Unfortunately most of us are stuck with where we're born.

I disagree some force is necessary force from a consequentialist perspective. No thats an observation, those are all activies states engage in and have a monopoly of, the fact that I didn't engage in double speak games, doesn't prove I was making a moral statement.

    Yeah, that is the only problem with this method. In life, you have a limited number of resources that you can use. So its not just try anything and see what fails, but try the most logical solutions and see what doesnt fail. That connects to the evolution thing too, thats why life is so rare in the universe (from what we know).

    I don't get a different impression from further re-reads. Your second comment seems to further justify this interpertation of the events. " but come now would you support a state even if you would know it would do some utilitarian good(what it DOES)? " . From a utilitarian perspective, the issue is weither a state maximizes what is "good" , "utilitarian good ", is different from "good". In that it assumes the cost benefit utilitarian analysis is in the states favor.

    Hi. Tim just needed to sum it as just another form of faith & reason. Representing both with 1 (Trial & error and God). There's no argument at all. Just use both you'll have a more complete answer:)
    (1)reason + (1)faith = 2
    (1)Trial and error + (1)God = 2
    You gain more by a good combination of two time tested (truths) tools: faith + reason. You try and get the error to form your facts things that work thing that don't, you try it once & sometimes get no error & then add faith as well. Gbu
