Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that social groups can make more accurate collective judgements than expert individuals?

Yes. Evidence across behavioral and decision-making studies supports the premise that social groups and collective judgments can match or exceed the accuracy of individual experts by aggregating diverse inputs and collaborative reasoning.

The analysis

The claim specifies that social groups can make more accurate collective judgements than expert individuals. Multiple papers in the literature (e.g., [0], [4], [8], [10]) validate the 'wisdom of crowds' or collective intelligence effect, showing that groups or aggregated group medians frequently outperform individuals, including experts, across various tasks. There are no papers in the retrieved set refuting this general phenomenon.
