But you would think we could pick up these sorts of mistaken judgements by simply introspecting and, in a manner of speaking, retrace our thought processes back to the original mistake.

Students were told the research was investigating teacher evaluations. Specifically, they were told, the experimenters were interested in whether judgements varied depending on the amount of exposure students had to a particular lecturer. This was a total lie.

Experimenters made sure it was obvious which of the lecturers alter-egos was more likeable. In one he appeared to like teaching and students and in the other he came across as a much more authoritarian figure who didn't like teach at all.

This was unsurprising as it backed up previous work on the halo effect.

The surprise is that students had no clue whatsoever why they gave one lecturer higher ratings, even after they were given every chance. After the study it was suggested to them that how much they liked the lecturer might have affected their evaluations. Despite this, most said that how much they liked the lecturer from what he said had not affected their evaluation of his individual characteristics at all.
For those who had seen the badass lecturer the results were even worse - students got it the wrong way around. Some thought their ratings of his individual characteristics had actually affected their global evaluation of his likeability.
Even after this, the experimenters were not satisfied. They interviewed students again to ask them whether it was possible their global evaluation of the lecturer had affected their ratings of the lecturer's attributes. Still, the students told them it hadn't. They were convinced they had made their judgement about the lecturer's physical appearance, mannerisms and accent without considering how likeable he was.

We quite naturally make the kinds of adjustments demonstrated in this experiment without even realising it.

Are you really evaluating the traits of the person or product you thought you were? Alternatively is some global aspect bleeding over into your specific judgement?

Or perhaps, even if you do check, you'll still never know...Gulp. (Здесь непонятно, что означает слово Gulp)

The halo effect in itself is fascinating and now well-known in the business world. According to 'Reputation Marketing ' by John Marconi, books that have 'Harvard Classics' written on the front can demand twice the price of the exact same book without the Harvard endorsement. (Здесь слово front переводится как фронт?)
