This is endemic to all the sciences, not just the social ones. Biology has just as poor (if not worse) an understanding of stats, and even worse pressures in terms of the money at stake (medicine, pharmaceuticals). Maybe physics, and to some extent, chemistry, are immune, I'm less familiar with them. The issue is less stats, and more the pressure to publish, file drawer effects, poor career prospects for replication work relative to original research, fishing without multiple comparisons correction, etc. etc. etc. All of which combines to result in a lot of scientists looking the other way because the rules for stats and the rules for tenure aren't in alignment. I saw all this first-hand when I was a grad student in cognitive neuroscience. Don't for a second believe this is limited to psychology. If anything, psychology is being more honest and grappling with these issues first.
