There are no double-blind studies. All evidence so far is largely anecdotal, because it's extremely challenging to get a statistically significant number of people to do this to themselves at the same time.

I didn't ask for double-blind studies. I was saying that I understand the rationale behind it ( so no need to repeat it it again) but am not convinced unless there is some evidence.

There is a myriad of statistical evidence about how sleep deprivation works, but by and large most people just report "if you don't get X hours of sleep per night, then things suck".

How is this related? We are talking about this method versus more 'traditional' methods of adapting to everyman.

Based on many anecdotes (which are spread around in personal correspondence, forums, listservs, etc) the instructions above make sense. It is the best data available ...

Granted, I have not been heavily involved in the related communities for the last ~5 years but I have seen significantly more people adapting everyman through the standard method of just jumping in (or jumping in and making some slight alterations at least). Fwiw, if you can provide the information that you are talking about here it would've sufficed to some extent as evidence (or at least data).

But we have to start with a hypothesis, and based on the anecdotes, this is that hypothesis.

You are assuming that based on the anectodes this is the optimal(ish) hypothesis but you have not provided them. If you wish I can link you (after some googling) to a lot of people who claim to have achieved everyman through more traditional methods for example.

My uberman adaptation using the 6nap one (with sometimes 1 extra) failed, but years I later successfully adapted to everyman using the 12nap method. So this collective experience means that I have evidence that this adaptation plan is a solid one, it's just not easy to impart to you.

The biggest difference between the two attempts is that in one you were going for uberman and in the second you were going for everyman. This, I suspect makes a bigger difference than the use of 6 versus 12 naps.

ETA: My point here is that if we insist on having evidence before we do experiments, we will not do a lot of science today.

Who exactly is insisting on that??
