Having had my tea, I decided it was time to write a new textbook of psychology. I decided that, to make the task more manageable, I would cut out: all historical introductions; all hypotheses however engaging which were unsupported by relevant confirmatory findings; all individual studies unless they illustrated a general point which had been replicated many times; most individual studies unless they were on substantial and highly representative samples; and all studies where either the hypotheses or the methods or the analysis of results were not clearly specified, and had not been replicated at least three times.
This is what I have got in my draft outline so far:
Chapter One: Psychological Theories which are non-trivial and well supported by results.
Any suggestions as to what I should include?
