RNG Training Experiment Idea.

Thanks for those thoughts and insights Doug - there's a fair bit to chew on there.

I'll just mention this information quoted from the site we're talking about:
https://psychicscience.org/random.aspx
There's no explicit mention of anything done in addition to the above - though we can't rule it out without asking the site creator for comment.
edit: Or perhaps by analysing the javascript code itself, which should be available in order to be executed by the browser.

Actually, Typoz, there's another, simpler way to introduce some dynamic randomization into code for online psi tests. It is to generate a new seed number each time a decision button is clicked. A Web server's time stamp can be used as the extraneous random input to generate the new seed number. That's how Dean Radin's GotPsi tests are randomized, as I learned recently. It wouldn't surprise me to learn Michael Daniels uses the same method for his tests.
