He has no expertise on this issue, and his article has been panned by the real experts in related fields who collectively have hundreds more years of experience and understanding.<BR/><BR/>My personal feeling is that he is an immature scientist who greatly overstepped his bounds in trying to generate flashy press-friendly claims.Johnhttps://www.blogger.com/profile/18114466143000554194noreply@blogger.comtag:blogger.com,1999:blog-7691251033406320222.post-91579760019713421422009-02-04T15:12:00.000-08:002009-02-04T15:12:00.000-08:00I'm always suspicious of gizmo idolatry.I'm always suspicious of gizmo idolatry.Catherine Johnsonhttps://www.blogger.com/profile/03347093496361370174noreply@blogger.comtag:blogger.com,1999:blog-7691251033406320222.post-56923453442812257202009-02-04T15:11:00.000-08:002009-02-04T15:11:00.000-08:00I believe it.I have not idea whether there is also...I believe it.<BR/><BR/>I have not idea whether there is also a war between two camps as well.<BR/><BR/>Brain scan data has always seemed oversold to me, though I'm not in a particularly strong position to reach that conclusion.<BR/><BR/>Nevertheless, when I was at NAAR, scientists routinely told me they thought brain scans were bunk.<BR/><BR/>Now that was several years ago, and I've been told that scans are now much better than they were -- but on the other hand I'm wondering whether people have told me that the big improvement was the fMRIs.<BR/><BR/>I don't remember.Catherine Johnsonhttps://www.blogger.com/profile/03347093496361370174noreply@blogger.comtag:blogger.com,1999:blog-7691251033406320222.post-64740464804434865392009-02-04T07:36:00.000-08:002009-02-04T07:36:00.000-08:00I've talked to two neuroscience friends who are an...I've talked to two neuroscience friends who are angry at this paper; they think the underlying issue is really a political war between various camps. <BR/><BR/>that said, i immediately believed it, because when i was working as a physicist trying to detect explosives in luggage, we made exactly the same mistakes in our algorithms (back then I'd not gone to CS grad school, and no one in our company knew anything about algorithms, and precious little about probability.)
