Check out the two posts by Galit Shmueli over at Bzst on hypoth­e­sis tests: one on the value of p-values and another on one-sided tests.

She says “Shock­ingly enough, peo­ple seem to really want to use p-values, even if they don’t under­stand them.” That mir­rors my expe­ri­ence too.  Con­fi­dence inter­vals are much more use­ful because they pro­vide a mea­sure of the size of an effect, rather than test­ing if it is equal to some pre­spec­i­fied value.
