Psychological Statistics

One fascinating thing about working in the area of psychological statistics is how hard it is to move people away from reliance on bad, inefficient or otherwise problematic methods. My own view - informed to some extent by the literature, by experience and by anecdote is that it isn't sufficient merely to establish than the standard approach is wrong. It isn't even sufficient to provide an obviously superior alternative. You also need to three other things: i) get the message out to the people using the method, ii) reduce barriers to implementing the method (provide user-friendly software, easy to understand tutorial sand so forth), and iii) get the new method taught at undergraduate or masters level.
