What the data shows
bankers were trusted in 2005 (41%)- Jev remembers Americans as more distrustful than they were. Its guess is below the real share for 98% of the figures, by 11 points on average, and within 5 points for only 18%.
- The gap is biggest for business professions: bankers (23 points too low on average) and accountants (22), then lawyers and real estate agents (about 14 each). It's smallest for car salespeople (3) and pharmacists (4).
- Its history is flat. Jev's estimate for a profession changes by less than 5 points in 62% of the five- and ten-year spans.
- But it knows which way things went. In all 4 spans where real trust moved by 5 points or more, Jev's change has the same direction, only smaller: bankers dropped 18 points between 2005 and 2010, Jev 5.
What it means, and what it doesn't
Jev's picture of past public opinion is gloomier and flatter than the record: it assumes Americans never trusted bankers much, when in 2005 about four in ten rated them highly. That fits its current ratings (see "Which professions Jev trusts"), where the professions it distrusts get almost no credit.
It doesn't mean Jev can't recall the polls at all; it gets the direction of real changes right. It means that when it describes the past mood about a profession, it will likely understate how much trust there used to be.
