The obvious, egocentric explanation for why we do this is that it makes us feel better about ourselves. But there are at least two other more innocent explanations, which are based on subtle flaws in our thinking.

The first possibility is that we find it easier to consider the favourable evidence for a single person than we do for a whole group. Consistent with this is the finding that people tend to be biased when comparing any single individual, not just themselves, against a group of others.

. In other words, it is the difficulty we have thinking about the favourable evidence for groups, as opposed to individuals, that seems to be the crucial factor underlying the "above average effect".

America in flames? Sound familiar? The closing lines of Grine Kuzine are really no different from Barack Obama’s former pastor Jeremiah Wright’s “God Damn America” paraphrase of Irving Berlin’s maudlin patriotic tune God Bless America. As a singer of Grine Kuzine, and as a not-too-distant descendant of her fellow immigrant workers, I do not understand the recent hysteria over the U-Tube posting of an out-of-context video excerpt of one of Wright’s old sermons. Jews and Blacks and even the whitest-of-white Americans have the right — and maybe the obligation — to be enraged at polities and policies that misuse or deceive them or that fail to live up to their potential or rhetoric. The hyperbole of songs and of sermons generates reflection and vents steam and diffuses rage even as it broadcasts it.

Far more interesting and insidious than the slips-of-the-lips of members of Obama’s confessional circles is Hillary Clinton’s decades-long involvement in an oligarchical right-wing prayer breakfast group called The Fellowship, Sound like the stuff of crank conspiracy theories? Writer Jeff Sharlet of The Revealer, a New York University weblog covering religion and the media, has just completed a book on the subject. Will apologies and statements of distancing and denunciation of The Fellowship be forthcoming from the Clinton campaign? I doubt it.
