Primes¶
- Nucleation
- The critical-nucleus size is the prime's analogue of the critical radius: an adopter cluster below a threshold dissolves as early users abandon an un-reinforced choice, while above it the cluster grows into a cascade — the empirically estimated "critical fraction."
This sourceEmpirically estimates the critical fraction of committed individuals (about 25%) needed to nucleate a cascading change in social convention — the social analogue of the critical nucleus, including persistence once the critical size is exceeded.
Supported in partVerified against the publisher's abstract
The source's abstract reports that a committed minority of roughly 25% of a group could tip the majority's opinion, supplying the empirical critical fraction but not the below-threshold dissolution mechanism.
“When the number of confederates was roughly 25% of the group, the opinion of the majority could be tipped to that of the minority.”

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 1 of 1 citation: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
