"Luck" just means we don't have enough information to say why so you use a statistical model instead. In the same way we treat winning a coin flip as due to luck but you could devise a situation where you know exactly what wi

The most interesting part of this to me is that, even though this evidence is extremely weak, it is actually stronger than the evidence from animal studies that tobacco smoke can cause lung cancer. It is nearly impossible to devise a stud

There is a difference when it comes to politics. Politicians take a dimmer view of bribery and smear campaigns when they occur outside an election season context.

Ha, yea. Here is the calculation I did (carelessly): > 128/54 [1] 2.37037 Still, one a week seems high.

Thanks, I saw that same value after a quick search but wasn't sure about it. That seems a bit high. So if you have 128 gb, you would expect 128/104 ~ 2.5 bitflips per week, about every other day?

No, the best you can do is a find a recent review article. Only rarely will you find direct replications in the case of medical and social research though, so as a heuristic you can just assume the evidence for everything is weak. Also, thi

The neutering isn't that bad, you can still get an improvement by adding more cores. Here's some of my results on a task doing a lot of string comparisons (plus some other stuff): https://image.ibb.co/ecH9VL/c

1) Hypothesis testing, significance testing, and NHST are all different things 2) P-values seem ok as a way to check how well your model fits the data. The problem is testing a strawman model/hypothesis.

I'm speaking from what I saw in the LIGO and CERN (Higg's Boson) papers. They spend way too much time on rejecting some questionable model of the background rather than testing actual predictions. From media interviews, I'll

Great to hear you are interested in this problem. It is a huge one that goes mostly ignored. Afaict, the p-hacking/etc people usually focus on are red herrings caused by the incompatibility of NHST and scientific research. Eg, it is go

From what I have seen it is quite simple. 1) There is this pseudo-scientific methodology called NHST (null hypothesis significance testing) devised pretty much on accident in the 1940-50s that tricks people into thinking they have discovere

I would put 100g as the upper limit of what you would eat on a low carb diet in a day.

>"Don't eat excessively" Yes, a low carb diet makes people feel less hungry, so they eat less. A (supposedly) "normal" carb diet makes many people hungrier than they should be so they eat excessively.

Yes, you simply consume less calories on a keto diet because you feel less hungry. For whatever reason consuming carbs over a certain threshold is addictive. Either way, they did not include a keto diet. Instead they used a "relatively
