Why replication matters in research
Launch library · evergreen read

Replication means an independent team, working separately, arrives at a similar result using similar methods to the original study. It matters because any single finding can be shaped by chance, by a specific sample, or by choices particular to one research team, none of which guarantee it holds elsewhere.
A finding that replicates across different teams, settings and populations earns a stronger claim to being a real, general pattern rather than a quirk of one particular study conducted once. Findings that fail to replicate are not necessarily false, but they clearly deserve more caution before being relied upon further.
For a campaign, favouring claims that have been replicated, where that information is actually available, is a modest extra step that meaningfully strengthens the credibility of the wider case being built, even if it means leaving out a striking but still unconfirmed early result that would otherwise be tempting to use.
