There's a mental aspect (chalk = business time) but it's not a placebo. Have someone deadlift with a particular grip with and without chalk, and they'll lift more with the chalk, no question. It helps grip.

Can anything literally be only part placebo? obviously hyperbole, but anyone who has stuck their hand in a chalk bag knows how comforting it is in spite of it being the 7th time on that same rest hold.
