Although social surveys suggest that racist and sexist attitudes are becoming less widespread, the facts show that discrimination and inequality persist. The cause of this phenomenon is both structural and individual: structural inequalities are reproduced by individual behaviours in an unintentional way, guided by implicit associations. However, the influence of these implicit biases on behaviour is not irremediable. Individuals can exert some control over their implicit associations in experimental settings, and it appears that improving individuals' ability to control their implicit biases can also help to reduce discrimination.  However, the factors that facilitate or inhibit this control in more complex contexts remain poorly understood. Our project aims to systematically investigate the ways in which implicit biases are generated and the contexts that facilitate or inhibit their expression. In particular, we will manipulate two dimensions of context: mental load and the personal consequences of decisions. By revealing the conditions that favour the emergence of biases or their control, this research has the potential to inform strategies in favour of fairness and equality.
