    Kant asserts that the category of causation exists in the mind prior to observation? Then why is everything not caused? In other words does observation confirm causation; or does causation confirm observation: nothing that we observe is uncaused? There are no conscious perceptions that aren't caused, according to Kant, it's just that we have to correctly identify the causes? Observation only sees things that are caused but, at the same time, does not reveal those causes? Then what does confirm the cause? The mind? Isn't that the same position as Hume? No. So, according to Hume, observation hints at causation but it is the mind that imposes causation. Causation is really constant conjunction of observations being assumed by the mind as having necessary connection- causation. The mind imposes causation by assumption, not necessary connection. The mind imposes causation by short circuiting expectations and imposing necessary connection where none exists. Causation, according to Hume, is an illusion based on a lazy mind trying to save energy by imposing order on a chaotic Nature trying to kill it. Causation is a survival strategy of a being with limited energy and abilities. A necessary assumption for a being with limited means. Whereas, according to Kant, observations are entirely necessarily connected- caused. The mind's role isn't to impose causation but to expose the causal links. Instead of "assuming" causation the mind deduces causation by experiment in order to narrow down the causal relationships that most matter. Causation isn't an assumption of a lazy, evolutionary burdened, mind but a deduction of a rational, evolutionary burdened, mind. So, according to Hume, observation doesn't confirm causation. It can never confirm causation. It can only assume (impose) causation based on limited means trying to conserve energy. According to Kant observation does confirm causation, it cannot help but do so because it is inherent in everything that can be observed. However the causal "relationships" must be sussed out, and this is done by the mind through experimentation and reasoning. Instead of an assumption by a mind with limited means it is a deduction/induction by a mind with time for experiments.

    Crisis of absolutism. Hume was on his way to relativity thinking, a pre-Einstein if you will. In the world there are connections all the time, and knowledge is based on this. Our language describing Nature’s workings is the issue here. Hume’s theory of causality is bad logic. And doesn’t understand how our brain works. Once you abandon “necessary” and “guarantee” logic, we move forward. Just observe and describe then share and discuss the descriptions.

    Very cool video. I am currently struggling with a mixed factorial ANOVA in JASP. When I run the ANOVA, the F statistics match my output from SPSS (so the data is entered correctly), but a VERY non-significant interaction (p = 358) keeps returning a bayes factor moderately in favor of the alternative hypothesis (3.05). Any help would be greatly appreciated.

    There is a mistake. The prior for the alternative hypothesis is too diffuse. This is Lindley's paradox in reverse. The Bayes factor of 3 trillion (!) should be a red flag that something is terribly wrong. If one prior has much lower entropy than another (spike vs normal distribution), then it will almost always yield a lower likelihood unless you get lucky. You're guaranteed to reject the null.

    Thank you for this video, it is really interesting to see the mechanics of this. I know you are explaining how Jasp does this job, but can you elaborate on where P(data | M,θ) comes from? Also, is P(θ|M) equal to 1-cdf of a cauchy distribution centred on 0 with scale 0.707? I would like to be able to go through this "by hand" to fully understand how the analysis works. Would appreciate any help

    What does it mean to say that there is a necessary connection between causes and their effects? Why does Hume think that we cannot justify our belief that there is a necessary connection between causes and their effects? Does Hume think that causality does not occur in reality, or does he just think that we cannot justify our belief in causality? Was Hume's skeptical point about induction really just that induction cannot guarantee certain knowledge? That seems like an obvious point, because no inductive inference that I make is guaranteed to be true. If a moving billiard ball collides with a stationary billiard ball, the stationary one is not guaranteed to move (it could be glued to the table, for example). Is that really all Hume was saying?

    Hi I recently ran several Bayesian independent samples t tests using the informed prior vs the default prior. I understand why the same analyses using the informed prior gives a bigger Bayes factor compared to the default, but I didn’t expect the effect sizes to all be smaller (and credible intervals narrower) when using the informed prior. Does anybody know why this might be?

    This is a very interesting topic and there are not too many alternatives on UA-cam but the acoustics are really bad (echo) and all the pauses, ehms and started anew sentences make it difficult to follow. It seems like this could be massively improved at not too high cost.
