Citation please.  My experience is that there are a lot more MDs and PhDs in biotech than other tech fields.  I would like to see where you got the information that a &quot;significant number&quot; have absolutely no science training.  Also, when you say &quot;significant number&quot; do you mean less than other fields at a significant level or do you mean less than some number you are defining as significant.  If the latter would that be only 5, 10, 15, 20, 49.9% without science training and is that less than average or other tech fields?
