That makes sense, I guess all of the other unknown variables would serve to dither the low resolution data and it would work for the same reason that CDs sound good with only 16 bits of resolution.
I am going to begin a random placebo controlled trial of melatonin use, quantified against my ZEO and work logs. I just need to find some opaque capsules.
Thanks. The experiment starts today. I made up 14 pills and randomized them with R code, under the assumption that I couldn’t possibly subconsciously track each pill and then remember their locations. In hindsight, this is probably more labor intensive and error prone than the method you used to randomize your adderall...
I start with a 14 tray pill box with treatment (0.75mg melatonin + parsely) in the first 7 boxes, and placebo (parsely pills only) in the last 7. I randomly reorder them 3 times, according to each of the lists outputted by my code, and it writes the final pill locations to a text file.
Here’s my R code for randomizing “single blind” placebo controlled self-trials:
Interesting procedure. I’d agree it’s probably much more work than some simple physical procedure. (I’d also point out that 14 pairs won’t give you much significance—my above power analysis suggested that for awakenings, anyway, you’d want more like 140 pairs. But I should be happy you’re actually doing the experiment.)
Hey gwern, as you predicted I didn’t have enough data to learn anything… and I didn’t have time to do it longer. I considered repeating it, but now I’m scared off melatonin until I learn more about how it works. Dr. Ray Peat theorizes that it might have some negative health effects by inhibiting oxidative metabolism:
Also, anecdotally I don’t really see a huge benefit to melatonin. Even small doses (0.75mg) seem to make me slightly groggy when I wake 7.5 hours later. I may have unusually slow melatonin metabolism, as I have the “slow caffeine metabolizer” P450 CYP1A2 variant, the same enzyme responsible for clearing melatonin.

I look forward to your results.

Here’s my R code for randomizing “single blind” placebo controlled self-trials:
sampleSize ← 14
intialSetup ← c(rep(“treatment”, sampleSize/2), rep(“placebo”, sampleSize/2))
reorder1 ← sample(1:sampleSize, sampleSize, replace = FALSE)
reorder2 ← sample(1:sampleSize, sampleSize, replace = FALSE)
reorder3 ← sample(1:sampleSize, sampleSize, replace = FALSE)
final ← intialSetup[reorder1][reorder2][reorder3]
write.table(final, “final.txt”)
paste(reorder1, “->”, 1:sampleSize)
paste(reorder2, “->”, 1:sampleSize)
paste(reorder3, “->”, 1:sampleSize)

I plan to do much more than 14, but it was very tedious to set up so I started with that. I need to streamline the procedure.
How has the experiment been going?
