How to systematically approach truth - Bayes' rule

The philosopher Gottfried Wilhelm Leibniz had a dream. He hoped that progress in philosophy and mathematics would eventually yield a method to systematically figure out the truth. This video explores an approach to that dream that takes us some of the way there: Bayesianism. The basic idea of Bayesianism is to represent beliefs as probabilities and update them using the formal rules of probability theory to the best of our ability. In particular, Bayes' rule tells us how to update our degree of belief in a hypothesis after observing some evidence. Bayes' rule can inform many central tenets of scientific reasoning. One example is Cromwell's rule, which tells us with the language of probability theory that our empirical beliefs shouldn't be absolute dogmas, but always potentially put into question when new evidence comes in.

Many of our future videos will probably be more comprehensible if you understand Bayes’ theorem and assimilate Bayesian thinking. If you found the grabby aliens’ videos somewhat confusing, try to go back to them after having understood this one!

@davidlovesyeshua Год назад

@@SeektheLordsface Ok, I'll bite. Let's think about Jesus using Bayesian probability. The observed likelihood of people coming back to life after dying is pretty tiny since there are no agreed upon/verified examples. The number of people who have been observed and verified to stay dead after dying is easily in the millions as a lower bound, although plausibly you could use a number of billions since it doesn't seem like anyone has physically come back to life in the last few centuries and billions have died in that time span. This gives us somewhere in the 1/million to 1/10 billion range for the prior probability of Jesus coming back to life after dying, regardless of whether a God exists since that God evidently usually doesn't raise people back to life. What evidence is cumulatively strong enough to give better than 1 million times stronger support (likelihood ratio) to the hypothesis that Jesus truly rose compared to alternative hypotheses like a couple of the disciples lied or had grief hallucinations that moved the other disciples to true belief in his resurrection?

@gabbiewolf1121 Год назад

Really love this content as someone who took stats and has heard of Bayesian epistemology but never really delved into it :D I'm sure the Bayesian community has already addressed this, but I think I would recommend at least one alteration to the rule of excluding one and zero from your set of probabilities. I think that either tautologies and contradictions should be excluded from the domain of your probability functions or your probability function should have the property that 0 is assigned to and only to contradictions and that 1 is assigned to and only to tautologies. The first option would definitely be better.

@DavidSartor0 Год назад

I disagree with this. I'm not sure how to elaborate, sorry.

@HuseyinOmerErgen Год назад

A common view is that you can never be 100% sure that a statement is a tautology/contradiction. While your analysis may say that something is definitely a contradiction/tautology and therefore false, the probability you give it should never be 0 or 1 because your analysis is not perfect. The result may seem counter-intuitive but everyone makes mistakes in reasoning. Consider this, can you correctly identify a contradiction EVERY TIME when given 5000 contradictory and 5000 non-contradictory statements? It seems to me that almost everyone will make at least one mistake. Even if we say that some people are just so good at logic and they will never make any mistake in a task like this, someone being one of those people will never be 100% certain. So in that case as well we cannot (should not) assign probabilities of 1 or 0 to statements. Another reason to not give them probabilities of "0 or 1" is that once you have done that, mathematically, you can never be convinced otherwise. If you incorrectly called something a contradiction and gave it a probability of 0, nothing should ever be able to change your mind since 0 times anything is 0. Same for giving something a possibility of 1. Once you made an incorrect call game is over and we will make incorrect calls because of the reasons I articulated above.

@DavidSartor0 Год назад

@@HuseyinOmerErgen Thank you. Real things have logical uncertainty.

@davidlovesyeshua Год назад

@@HuseyinOmerErgen This is the correct analysis. To make it a bit more obvious, you can consider the possibility that your brain is struck by cosmic rays in just the right way at just the right time to cause you to misidentify a tautology, even if under normal circumstances you think you ought to be incapable of making a mistake on something that easy to identify. Or if cosmic rays aren't enough, some undiscovered property of dark matter/energy, a side effect of advanced alien tech probing your mind, cartesian demons, etc. There's just no practical use or philosophical justification for probabilities of 1/0 when we can just say "for all practical purposes this is effectively certain even though it technically isn't" and move on. Although that does actually make me think of 1 motivation for 1/0 probabilities and that's use in mathematical models, but that's easily solved by distinguishing between in-model and out-model confidence. I can make a model, plug numbers in such that something has a probability of 1, and then simply assign less than 100% credence to the model itself being accurate.

@kit-san4846 Год назад

I'm honestly shocked that this isn't more wide spread, at least not that I've noticed. While I doubt it (or anything truely) could have been a cure all, it genuinely feels like it could have lept us forward in how we approach the world as a whole. The best part of this is that it can challenge itself. Set H as the possibility of it working out for the better of the majority with e being the evidence. Since from what I understood, you start with H first before looking at the evidence and it would be harder to set than your examples. If I had to, I would use what would make the most sense from what I understand of Bayesianism and what I can reasonably conclude about it. Then I go into the evidence to adjust my probability and thus by its own rules, we can determine its effectiveness and how confident in its method. There are probably some errors in this as I am just learning about Bayesianism from this very video, but I hope I got my point across. Heck you could probably make that into a Baye's equation. To me at least, a formula that can challenge itself with its own rules is HUGE, doubly so as it asks us to never be 100% or 0% sure about anything. Like you said with the moon being made of green cheese, it can prepare us for when that 2% ends up being reality. It would be like the difference between a bridge suddenly but slowly collasping to a bridge just suddently dissappearing from under out feet (paws). Sure, neither are ideal, but one gives us more time to react to safety than simply dropping us toa our doom, hopping for that 1% chance of surviving that fall becomes reality.

I feel you, adhd brain here as well. What I noticed though, for some problems my brain actually requires way more information than I think to make a decision. You need a certain threshold of input information to synthesize it into a new pattern. Basically the way you need a certain amount of whatever for emergence to do its thing and turn quantity into quality. And the more diverse information the better. Not every decision needs to be taken this way (in math equations) and I like that one doesn't need to know super advance math to understand how it works and apply it, just logic!

In real life there are a tiny fraction of beliefs for which the required probabilities to complete these calculations are knowable, and of those a similarly tiny fraction are known. The vast majority would require estimates which are largely subjective. So the true value of the formula is not in broad applicability of the actual calculations, but as a means of understanding the sorts of information we should consider in making rational decisions, and how that information interrelates.

Conditional probability to me has a lot in common with Quantum math , namely that I can stare slack jawed at it and listen to explanations all day long and nothing ever sticks. And this despite my being quite comfortable with some damned abstract math concepts like Group Theory, Category Theory (abstract algebra in general), GR, Calculus, Algebraic Geometry, Topology, etc. I can grok that conditional probability and bracket notation are actually incredibly simple in and of themselves. Shockingly few moving parts, on a par with ordinary ratios. But I still look at them and feel like Meatwad from Aqua Team Hunger Force floating about in the ocean saying "Do what now?". :(

A fair coin does not have a 50/50 chance of landing on a particular side. Coins have an edge which is a factor. Though it's essentially negligible it still has an effect on the outcome. And there have been time when coins land on their edge, I've seen it

0:50 "This video will reach 1 million views within a year P~10%" Coincidence: Eliezer Yudkowsky claims he would've said 10%, if someone had asked him how likely HPMoR was to become at least as popular as it eventually did.

Information exists is shown by every form of evidence, whether it be empirical/induction, synthetic/deductive, apiori, posteriori, etc, so in a way it has infinite evidence just by evidence existing because alternatively nothing exists which is a self contradiction. Which leads to my question of doesn't some mathatical proofs count as infinite evidence like proof by contradiction or no because their deduction is based on axioms that you would say we should have some doubt because they are assumptions?

Bayes' rule is very useful in the field of history, but unfortunately it's not very accepted among historians. Perhaps in the future it will be.

About the 0% /100% stuff: I think the exceptions where you can be 100% certain are tautologies (stuff that can:t be false for purely logical reasons) and subjective experience as such (not "things are as we recognise them", but rather "I'm currently having some kind of subjective experience") The charitable interpretation of people saying they're 100% certain is that the difference is small enough so it doesn't matter if you aren't extremly nitpicky (like 99,99999%)

What if your probabilities are measured by qbits? By reducing every probability in the system to a comprehensive system of Booleans, a quantum computer should be able to produce a set of solutions. Consequently, measuring the number of each type of outcome against the total number of measured solutions would result in the probability that scenario would occur (I assume). Would this theoretically achieve the same result as the Bayesian calculations? Would it be more or less accurate? And can we even practically expand an arbitrary probability function into Boolean cases without accounting for every quantum measurement for every particle in the system in the first place? I wonder if a neural network could arrange such a complex Boolean directed graph from a description of the evidence and postulation… 🤔

In my opinion (strong emphasis on opinion) the benefit of this equation isn't the answer you get, it's the way you have to think to work the problem. It's an equation that teaches unbiased critical thinking.

@puppieslovies 2 года назад

I wonder if there will ever be people with radical ideas like this now that we live in a world where some things are known to be mathematically impossible to prove, but could be true. It seems like you would have to ignore that to assume all things can be proven

@olawlor 2 года назад

But incompleteness doesn't stop us from having a rational basis for making everyday decisions! (And there are some promising workarounds even for Gödel-type limits on mathematical reasoning, like expanding the true-false dichotomy to support self-referential statements like a Gödel sentence.)

@daffyf6829 Год назад

There must be something missing in the formula, something that assigns value or importance to the hypothesis. So in the burglary alarm example, having someone breaking into your house has a higher importance than a false alarm, lending it more credence. More so if your house had been robbed before and the experience was traumatic. To treat every alarm as true until proven false seems perfectly reasonable to me, and it is in fact how most public places behave. Giving value to the hypothesis would explain a lot of what we perceive as irrational behavior. That is, it could change our opinion of a person's thoughts or behaviors, and perhaps allow a more rational, productive discussion about it.

@rowbot5555 Год назад

That's risk assessment, not likelihood assessment. Something can be unlikely but still worth protecting against in the case that it occurs anyway.

To my mind the fact that 1 in 10,000 houses experience burglaries on any given night, does not mean: P(Burglary) = 0.0001. Maybe, if your house (or a house in your area) only gets burgled on average once every 27 or 28 years, then P(Burglary) = 0.0001 could be true.

Well now you should make a video covering a much more famous and much more well known law, Murphy's Law where anything that can go wrong will go wrong. Also nice use of using the classical music that Sam O' Nella used to use. Sam O' Nella: Hey Kids.
