> And how would you even double-blind test this anyway?
Get lights that either start fast and slow down or blink at speeds that randomly change then use serial numbers to track which lights are which, but send them out at random to test subjects?
Which treatment you're in is relatively easily detectable, so unfortunately that wouldn't work.
I like the approach though, it would be a reasonable control condition (assuming that the 60bpm is a core part of the effect).
you would blind the participants to the effect you are looking to measure. If they don’t know what to expect or what conditions there are, they can still get a placebo effect from random patterns.

Maybe. Generally you'd do a manipulation check at the end to ensure that people couldn't identify what condition they were in.
Additionally, that's single blind rather than double blind.
