Disgust & Contamination Tagging

Disgust is a fast, sticky evaluation that transfers by contact and association; anything paired with a disgusting cue, even briefly, is valued less and avoided.

An everyday example

Shoppers rated a product lower after it merely touched a package of feminine hygiene products on the shelf.

What it can cost you

Discarding a sound option because of an irrelevant contamination cue, or being steered away from a competitor by engineered disgust.

Warning signs

  • My objection is a feeling of 'ugh' I cannot attach to a fact.
  • The aversion started after an image or story, not after the terms.

One thing to do

When aversion arrives with a physical 'ugh', ask what it touched. If the objection is contact or association rather than substance, discount it.
