How to weigh a source's incentive to persuade
Launch library · evergreen read
Every source has some interest in how an issue is understood, whether financial, reputational or simply the natural wish to be seen as right about something they have argued publicly, and noticing that interest does not automatically discredit the source, but it does tell you what to check more carefully.
A source with a direct stake in a particular conclusion is not necessarily wrong, but its claims deserve the same scrutiny you would apply to any other evidence, ideally checked against independent sources that do not share the same incentive to reach that particular conclusion or outcome.
Being transparent about a source's incentives, including a campaign's own, tends to build more trust than pretending incentives do not exist at all. Audiences are generally forgiving of a clear interest as long as the underlying evidence still holds up once examined honestly and in full, which is ultimately the only test that genuinely matters here.
