I thought his results were too good to be true statistically, according to
modern analysis.  Further, I thought it had been suggested that this was 
likely to be because his assistant(s) knew what the boss wanted and made 
sure he got these results.  Can anybody confirm or refute (preferably with a
reference)?   Thanks,
