A little hedging there? Is anyone immune to these effects? I know I'm not but I really don't know the general answer. I'm sure there's some variation in susceptibility but does Mr./Ms. Sighted Objectivity exist?

The results I've seen for sighted vs. blind testing have been presented in statistical format - no breakdown for individual participants.

I've also heard anecdotes of people who were so confident they were unaffected by this psychological crap that they agree to do a sighted vs blind trial. I've yet to hear of a case where objecivity prevailed over psychology. But perhaps that's selective listening on my part.
