What's something you wish you knew before you ran your first study on Prolific?

Is there anything you wish you’d known before you clicked ‘publish study’?

That I would not be able to change any study details after I publish (and the current places are full), afaik, the issue I am facing currently.

That I would be well advised to add some trickier attention checks to see if participants are really really paying attention (even if participants must still be paid should they fail such difficult checks).

That the studies get responded to so quickly, that I could be more picky in my participant selection.
