Individuals who obtain higher scores on the Need For Cognition Scale (NFC) are less susceptible to the truthiness effect since they are less likely to use heuristics when determining if a claim is true. Conversely, those low in NFC are less likely to realize that photos paired with a claim are non-probative, which can lead them to believe that the claim is true using the truthiness effect. Age has also played a factor, and surprisingly, older people fall victim to truthiness less than their younger counterparts when judging more well-known claims. A possible explanation for this is because older adults have a more expansive knowledge network, but research has yet to prove this theory.
