Perhaps -- on the part of all the imitators after the first wave of enthusiasts. Considered from the imitators as samplers (and those after), perhaps we have a positive feedback loop of selection bias.Gus Van Hornhttps://www.blogger.com/profile/05126749051688217781noreply@blogger.comtag:blogger.com,1999:blog-8839412.post-17094014761219925672016-01-25T13:30:01.054-06:002016-01-25T13:30:01.054-06:00I think the phenomenon described in the bold text ...I think the phenomenon described in the bold text you quote falls under the broad heading of "selection bias". The assessments of the effectiveness of the new development methodology (or whatever) are assumed to be a representative sample of the overall results, but in fact they are not because there is a systematic tendency to exclude negative assessments from the sample.Kyle Haighthttps://www.blogger.com/profile/14608497826478356055noreply@blogger.comtag:blogger.com,1999:blog-8839412.post-43974888156673541692016-01-25T13:03:21.084-06:002016-01-25T13:03:21.084-06:00Sounds similar to "survivor bias".Sounds similar to "survivor bias".RThttps://www.blogger.com/profile/12839360630529589800noreply@blogger.comtag:blogger.com,1999:blog-8839412.post-30303372348144525712016-01-25T12:53:17.567-06:002016-01-25T12:53:17.567-06:00Hi Gus,

Part 'Bubble' (as in Dot-Com Bubble) and part confirmation bias, though in something of a collective sense rather than individually. <br /><br />Confirmation Bubble?
