In this 2018 GDC session, Epic Games' Ben Lewis-Evans discusses the science of human error and how error can be prevented or encouraged to help create your intended game experience.

It was a fascinating talk that refocused a lot of common game design problems through the lens of human psychology, and Lewis-Evans offered up a slew of intriguing suggestions for how to design your game's levels, encounters, and systems in ways that take advantage of the way we think through problems.
