- Extension neglect is a type of cognitive bias which occurs when the sample size is ignored when its determination is relevant. For instance, when reading an article about a scientific study, extension neglect occurs when the reader ignores the number of people involved in the study (sample size) but still makes inferences about a population based on the sample. In reality, if the sample size is too small, the results might risk errors in statistical hypothesis testing. A study based on only a few people may draw invalid conclusions because only one person has exceptionally high or low scores (outlier), and there are not enough people there to correct this via averaging out. But often, the sample size is not prominently displayed in science articles, and the reader in this case might still believe the article's conclusion due to extension neglect. Extension neglect is described as being caused by judgment by prototype, of which the representativeness heuristic is a special case. Forms of extension neglect include:
* base rate neglect
* insensitivity to sample size
* scope neglect
* duration neglect
* the peak–end rule
* the conjunction fallacy
* the less-is-better effect The extension effect is "neither universal nor absolute". If attention is drawn to set size in an easily interpretable way, an additive extension effect is reported, according to which the valuation of a set is a function of the valuation of a prototypical member of the set added to set size, rather than multiplied.

- Negligencia por extensión es un tipo de sesgo cognitivo que ocurre cuándo la mente tiende a ignorar el tamaño de un conjunto durante una evaluación para la que dicho tamaño es lógicamente pertinente. La negligencia por extensión es descrita como causada por juicio por prototipo, del cual la representatividad heurística es un caso especial. Las formas de negligencia de extensión incluyen:
* Negligencia de frecuencia base
* Insensibilidad al tamaño de la muestra
* Negligencia de alcance
*
* La falacia de conjunción
* El efecto de extensión no es "universal ni absoluto". Si la atención es enfocada en el tamaño del conjunto de forma que sea fácilmente interpretable, se reporta un efecto de extensión aditivo, según el cual la valuación de un conjunto es una función de la valuación de un miembro prototipo del conjunto añadido al tamaño del conjunto, en vez de multiplicado.
