  • [from steve_portigal] On The Media: "Debunk This!" (August 27, 2010) – [Pervasive myths affect product adoption as well as political or cultural stories. This is an area we are sometimes asked to explore] BROOKE GLADSTONE: Now, this study is building off previous research that you've done on correcting misperceptions, research. But can you give us just a quick rundown of what those earlier experiments showed?
    BRENDAN NYHAN: My coauthor, Jason Reifler, and I looked at can the media effectively correct misperceptions, which seems like a simple question, but no one had really tested that scientifically.
    BROOKE GLADSTONE: And you found actually that when people had their misperceptions challenged certain people, at least, were more likely to become more firmly entrenched in that belief.
    BRENDAN NYHAN: People were so successful at bringing to mind reasons that the correction was wrong that they actually ended up being more convinced in the misperception than the people who didn't receive the correction. So the correction was making things worse.

  • Report: Real-world police forensics don't resemble 'CSI' – Even before the popularity of shows like CSI, there was presumably a cultural belief in the "science" behind these techniques. But the report finds that:
    – Fingerprint science "does not guarantee that two analysts following it will obtain the same results."
    – Shoeprint and tire-print matching methods lack statistical backing, making it "impossible to assess."
    – Hair analyses show "no scientific support for the use of hair comparisons for individualization in the absence of (DNA)."
    – Bullet match reviews show "scientific knowledge base for tool mark and firearms analysis is fairly limited."
    – Bite-mark matches display "no scientific studies to support (their) assessment, and no large population studies have been conducted."
  • NJOY electronic cigarette – Looks like a real cigarette, complete with glowing tip on inhale, and exhaled vapor that resembles smoke. Gives an inhaled nicotine experience, while messaging to the rest of the world that you are really smoking a real lit cigarette. Paging Erving Goffman?

    Someone was using one a party last week; someone else got out their simulated Zippo lighter (an iPhone app) and lit it for them.
