# New Empirical Evidence on Disjunction Effect and Cultural Dependence

## TL;DR

This study provides new empirical evidence showing that the disjunction effect in decision making varies with culture and gender, challenging classical probability assumptions.

## Contribution

It introduces a new experimental approach with detailed statistical analysis and proposes classifications of the disjunction effect as strong or weak.

## Key findings

- Disjunction effect depends on culture and gender.
- Females exhibit a stronger disjunction effect than males.
- New statistical methods differentiate types of disjunction effect.

## Abstract

We perform new experiment using almost the same sample size considered by Tversky and Shafir to test the validity of classical probability theory in decision making. The results clearly indicate that the disjunction effect depends also on culture and more specifically on gender (females rather than males). We did more statistical analysis rather that putting the actual values done by previous authors. We propose different kind of disjunction effect i.e. strong and weak based on our statistical analysis.
