Research has shown that, within industry, diverse teams yield better results than homogeneous ones [1,2]. This is particularly true within creative or enterprising endeavors [3,4], which is characteristic of both research and entrepreneurship in the AI Med field.

A well-rounded team representing multiple different backgrounds and perspectives will find better solutions to problems and will generate more novel ideas than a narrowly constructed team. In his landmark study on cognitive diversity [5], Scott Page explains that when people think alike, they will get stuck at the same locally optimal solutions. 

Sheer intelligence is not as powerful as having multiple points of view to find new and better solutions and to help correct for human error and biases. As Nobel Prize-winning author and father of behavioral economics, Daniel Kahneman, put it: “We can be blind to the obvious, and we are also blind to our blindness [6].”

The field of AI, in particular, has been identified as requiring diverse participants in order to create the best models by avoiding problems with biased training data [7].

Gender diversity is not the only dimension of diversity required to achieve a well-rounded team. A group that exhibits cognitive diversity will likely also include people of different nationalities, ethnicities, religions, ages, and political views – generally speaking, people with different experiences and preconceptions.
