All contemporary science evidentially depends on folk psychology. For instance:
- it is assumed that other scientists tend to say what they observed, and "observation" is a term of folk psychology; the evidence that they tend to say what they observed is based on evaluation of their motives;
- it is essential to the modern scientific enterprise that one be able to assume that technicians are doing what they claim, rather than producing equipment that displays fraudulent results; but the evidence that they are doing this is based on theories about the technicians' motives;
- the concept of reporting depends on folk psychological concepts; if nobody has intentions, nobody reports any results; but the reports of others are central to contemporary scientific practice.
