Confidence is not competence

Why investor assessments should measure confidence and knowledge separately

Joint authors: Dr Clemens Chaskel · Alistair Hume · Lesley Li

A confident answer can conceal a knowledge gap. Hesitation can conceal understanding.

For investor-insight, product and advice-experience teams.

  • Understand what the primary research actually found
  • Use a four-pattern framework without labelling people
  • Design a support test that measures understanding separately

Selected primary references, explicit evidence limits and a practical brief to use with your team.

Measure confidence and answer performance separately; higher confidence alone is not evidence of better understanding.
