Repeated questioning of a competent rival's expertise and close scrutiny of their routine work wear down the rival's confidence until they become self-doubting and defer.
An example
Four months after a payments startup closed its $60 million Series B, its head of data science found herself defending every model twice. In the weekly product review, the new vice president of product asked her to walk the group through her reasoning one more time on a fraud-scoring change she had presented in full the week before. He did it again on the churn model and on a pricing test. He did not ask the same of the engineering or marketing leads. Each request began with 'I just want to make sure I understand.' By the third month she was preparing appendices for small decisions and had stopped proposing new work in the meeting. Her team noticed that she now checked her calls with him before shipping them.
Why it works
Each round of questioning makes asserting expertise more expensive and less rewarding, so the person under scrutiny starts to doubt what their competence is worth and to find silence the easier course. Every probe looks like legitimate rigor, so the pattern stays deniable until someone counts it. Once the target absorbs the self-doubt, they police themselves and the pressure is no longer needed. It works with regular access to the target, a culture that prizes rigorous questioning, and a target without strong outside reference points. It fails against someone with independent standing, allies, or authority over the questioner.
The thinking behind it
Lee Ross Lee Ross's Social Roles, Social Control, and Biases in Social-Perception Processes (1977) reported a quiz game in which people randomly assigned to write questions were rated more knowledgeable than those answering them, by the answerers and observers alike. Repeated re-justification requests put one person permanently in the answering role. Ross's finding explains why the questioner gains standing and the target loses it, whatever their actual expertise.
Leon Festinger Leon Festinger's A Theory of Social Comparison Processes (1954) holds that people evaluate their abilities by comparing themselves with others, especially when no objective standard is available. A target whose work alone is questioned compares herself with peers who pass unchallenged and concludes something is wrong with her work. A written record of correct calls and mentors who know the work supply the objective standard and the comparison group the move removes.
Warning signs
One person's work is re-justified in every review while peers' work passes unchallenged. Questions begin with 'I just want to make sure I understand' or 'walk us through it again'. Requests for detail grow out of proportion to the decision. The person under scrutiny starts over-preparing, checking calls with the questioner, and proposing less. The questioner has regular access and no formal authority over them.
How to defend yourself
Count the pattern, and keep your own reference points.
- Count re-justification requests against those made of peers, with dates. Asymmetry that has been counted stops sounding paranoid.
- Keep a written record of your calls and how they turned out.
- Answer once, completely, and point to the earlier answer the next time: 'I covered this last week; here's the link. What has changed since?'
- Rely on mentors, peers, and outside contacts who know your work and can tell you whether it holds up.
- If it continues, take the counts to your manager and ask for review standards that apply to everyone.
Resist over-preparing in response. Extra appendices tell the room the questions were warranted.
How a leader shuts it down
Apply one review standard to everyone, and notice when one person is asked to re-justify routine work that others' work escapes. Ask who is under unusual scrutiny and from whom. Give new or less established leaders mentors and visible sponsorship, the reference points this move depends on them lacking.
