It's a common and disingenuous criticism that registered reports disallow discovery. They don't prevent you from doing exploratory analysis, they simply require you to display it as exploratory rather than pretending that was your

The old-school method is to get a grip dynamometer and keep a daily log. If your grip strength suddenly takes a dive you need to take some recovery time. Lot's of other indicators seem to work too, eg resting heart rate, but grip stren

One way to think of it is in terms of the expected value of betting on being correct. Even if the bet only happens once ever, I still need a way to map how confident I am to how much I think the bet is worth. If I am willing to pay up to $0
