Fair enough. Do you know whether there are so many people who know statistics that some of them are unlikely to have access to a normal career track?
There may be several problems here. These are my guesses, without special/private data to back them up. I'll use psychology as the name of the field, but this isn't specific to psychology.
Lots of people know statistics, but to criticize the statistics of psychology articles, one would be well served to also be familiar with the subject matter of the field. A pure statistician criticizing psychologists, looking in from the outside as it were, would probably come across as arrogant or offensive, and wouldn't be listened to by psychologists much. Whereas if
Simonsohn, a social scientist, investigates bad use of statistics in his field.
A few good quotes:
Laugh or cry?:"He prefers psychology’s close-up focus on the quirks of actual human minds to the sweeping theory and deduction involved in economics."
This looks like a clue that there's work available for anyone who knows statistics. Eventually, there will be an additional line of work for how to tell whether a forensic statistician is competent.
