Less-Is-Better Effect

We sometimes prefer a smaller, more focused option over a larger, more valuable set.

The need to act fast Favouring simple options

The less-is-better effect is a reversal of preference that occurs when the lesser or seemingly lesser option is preferred when options are evaluated separately, but not when they are evaluated together (jointly). For example, people are willing to pay more for a smaller gift (a nice scarf) than a larger gift set that includes the scarf plus a cheap pen. The pen decreases the perceived value of the set.

Would you catch it?

Recognising a definition is not the same skill as spotting it.

Two scenarios from the app, with distractors drawn from the same family of biases — which is what makes them hard.

Scenario 1Which bias?

Maria is choosing between two gift baskets. One has 10 items, the other has 4 items but includes a rare cheese she loves. She picks the smaller basket.

Scenario 2Which bias?

At a restaurant, Fiona orders the chef's tasting menu of four exquisite dishes rather than ordering à la carte from a large menu.
