'Everything is relative': Comparison processes in social judgment

Thomas Mussweiler · European Journal of Social Psychology · 2003

Research-assisted source review

What it supports
When comparison makes target-standard similarities accessible, judgements tend to assimilate towards the standard; when it makes differences accessible, judgements tend to contrast away from it.
Where it may not transfer
This is an integrative theoretical account rather than a product experiment or pooled effect estimate. Teams still need a defined target, standard, measure and controlled comparison before applying either mechanism.

Ordered labels invite comparison between increasingly negative audience descriptions. Their sequence may influence where an ambiguous experience is placed, although that requires testing.
