Participants were given a disproportionate number of positive statements for projects A and C so each participant may be biased towards a more positive interpretation of the somewhat ambiguous statements (sufficiently ambiguous to cause 20% of individuals to make different judgements without that initial bias).

Even if the information was interpreted consistently by each individual, the benchmark of success is still biased against collaborative decision-making. The possibility that the collective judgment is different, and perhaps better, is precluded by the assumption that the group should reach the same judgements as individuals.

If the group produced more balanced or well-informed judgements due to the distribution of expertise, would that be interpreted here as a failure of information efficiency and "decision-making quality"?
