The claim in the post (which I think is very good) is that we should have a pretty strong prior against anything which requires positing massive market inefficiency on any randomly selected proposition where there is lots of money money on the table. This suggests that you should update away from very short timelines. There’s no assumption that markets are a “mystical source of information” just that if you bet against them you almost always lose.
There’s also a nice “put your money where you mouth is” takeaway from the post, which AFAIK few short timelines people are doing.
