introduce confounding factors

I agree.

I believe that we need an rct but without subjective wins from the gradually mounting evidence, the whole conversation is me pushing uphill for a cause that I'm only a bit motivated to prove to other people.

I'm confident for myself but the potential cause area needs more research.

I agree on the "if they have something to sell" but there really isn't much to sell here. Chew hard food, practice better posture and lip tape at night. It's not a financially viable industry to sell in.

Occasionally people sell gum. But they aren't rolling in riches in the process of selling gum.

Sometimes people facilitate accountability groups and there's a finance factor there but it's not very common. And that's a private coaching group, it takes work to maintain.

Yes photos are open to manipulation by lighting and some are like that but I don't think al... (read more)

Using different countries as cohorts introduces all sorts of confounding factors. People will put forward a biased case even without a financial incentive. Maybe a person genuinely believes that the weight-loss or skincare regimen they followed worked, and they want to put the best case forward so other people benefit from it, so they use the worst Before and best After photo to be more convincing. People who saw no difference won’t post at all. The reason RCTs exist is because time and time again we’ve seen that looking at anecdotes and individual case studies leads to conclusions that turn out to be wrong when you RCT them. Might seem nitpicky but you just end up wrong half the time otherwise.

I didn’t see case-control studies or cohort studies. You should link to those. Before and after photos are prone to manipulation and bias Take a photo with your jaw pulled back for the before and then one with your jaw projected forward for the after. Use better lighting for after. Even if the person is not consciously intending to, these are so easy to manipulate. Maybe surgery was done in some of those photos and the poster is not being forthcoming about that, if they have something to sell.

I've gotten a lot from Rob Burbea's 2019 jhana retreat talks (a).

I previously investigated the cannon and claims around commute times and found that the research cited didn't support those claims. I never wrote that up (sorry).

I came to question the cannon when I talked to all my local rats about how they commute and their preferences.

I found that contrary to the claims in cannon - people liked their public transport commute and were using it to read, talk to friends and generally enjoy their time to unwind from work on the way home. The research talks about time of commute but generalises from car driving and traffic s

Thanks for pointing this out. Research particularly seems to show that people who commute by bike are the most satisfied, followed by walking, then trains, then buses and carpools (which are almost as bad as driving): http://web.pdx.edu/~jbroach/654/homework/Smith_2013.pdf Personally, I normally commute by a combo of bike and train, and I find that on days when I have to drive instead it does add stress, especially if traffic is bad.

Can I get 5 karma so I can make a post? Thanks in advance.
