Claude: When I' m having lunch with job candidates, I watch to see if they salt their food without first tasting it. If they do, I count that against them, because they' re making decisions based on inadequate information. Larissa: That' s silly. It' s perfectly reasonable for me to wear a sweater whenever I go into a supermarket, because I already know supermarkets are always too cool inside to suit me. And I never open a credit card offer that comes in the mail, because I already know that no matter how low its interest rate may be, it will never be worthwhile for me.
The principle that "in professional decision-making contexts, those who have the responsibility of judging other people's suitability for a job should not use observations of job-related behavior as a basis for inferring general conclusions about those people's character" can most reasonably be interpreted as the principle that Larissa invokes to criticize Claude's policy through the two analogies she offers.
