...But there is barely beginning to emerge a new generation of creationists with legitimate and relevant credentials who are undertaking to actually do some of the painstaking, detailed drudgery that underlies any genuinely live scientific program. This emergence has begun to produce a separation in the creationist movement — an upper and lower tier, so to speak. I think that what ultimately separates the two tiers is different levels of respect for accuracy and completeness of detail, and different levels of awareness that a theory's looking good in vague and general form is an enormously unreliable predictor of whether in the long run the theory will be disemboweled by recalcitrant technical details. That appreciation is something that typically comes only with a legitimate scientific education, which some of the creationist popularizers and many in their audiences lack...The newly emerging upper tier of the creationist movement, however, seems to have little patience with the vague popularized treatments and is, again, undertaking to do the meticulous detail work that a genuinely scientific creationism requires. As yet, this upper tier is not associated with any particular organization.
