Bias, Consistency and Decision Documentation · Lesson 1

Recognise how judgement drifts

Course overview · 4 min reading + 12 min practice, estimated

Principles and method

Bias can enter through requirements, sourcing, evidence collection and interpretation. Familiarity, prestige, first impressions and a single striking example can distort the weight given to evidence. Awareness alone does not remove these effects. Build process controls: explicit criteria, independent scoring, structured questions and review of inconsistent decisions. Avoid using the word bias as a substitute for investigating what happened. Ask which information influenced a judgement, whether it was relevant and whether comparable cases were treated similarly. The goal is a more defensible process, not a claim of perfect objectivity.

Worked example

A panel treats a famous employer as proof of leadership. Reviewing the actual evidence reveals that one candidate’s role was narrow while an applicant from a smaller firm owned the relevant decisions.

Put it into practice

Identify three judgement traps in a fictional shortlist discussion and propose a process control for each.

Use fictional information and keep your work in your own notes.

Compare your approach: self-review guidance

Link each control to the mechanism of error. For prestige effects, require evidence of responsibility. For early impressions, score criteria before an overall recommendation. Avoid relying only on a reminder to be fair.
