An especially common version of this phenomenon is what psychologists call denominator neglect. If you want people to be impressed by an amount, choose a large scale (“$365 a yearβ); if you want them not to be impressed, choose a small scale (βonly a dollar a dayβ). The effects of strategically choosing the right scale (i.e., the right denominator) can be dramatic. In one study, respondents judged a disease that kills 1,200 out of every 10,000 afflicted individuals to be more dangerous than one thatβs twice as lethal, killing 24 out of every 100.
