Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Adding noise to one partner's signals eliminated the group advantage, but this disadvantage did not occur when confidence was communicated non-verbally. → Frith Chris D 2012

q2 · i? · review · r2
Experiments (Bahrami et al., as reviewed here) degraded one partner's perceptual ability by adding noise. The review reports loss of group advantage with unequal partners under free verbal communication, but that a supplied non-verbal confidence system "eliminated the disadvantage of working with a less-competent partner".
"This loss of advantage occurred even when the noise was always added to the same individual in the pair so that his performance was consistently poor. This effect critically depended on how the partners communicated their confidence."
Discussion¶
Related Claims¶
- Interactive engagement requires both partners' utterances to be primarily constructive and a sufficient degree of turn taking — related
- Students who were not surveyed for the study did not respond to the ability signal — related
- Two people discussing perceptual decisions can outperform the better individual, via weighted confidence sharing — a broader claim this one bears on
- Pairs rapidly develop shared verbal confidence scales, and faster development predicts greater group advantage — related
- Individual acceptance of group constructions depends on reflection and reconciliation processes triggered by differing opinions, sometimes occurring after the group session — related
- Optimal play in coordination games requires estimating a partner's degree of recursion and one's certainty in that estimate — related
- Sharing perceptual experiences through discussion improves individual performance beyond mere task practice — related
