From Cave to Cage? The Evolution of Housing Complexity and the Contemporary Dead End for the Human Brain

The evolution of the ever-changing neuroplastic human brain is inseparably linked to its environment. While early humans evolved in response to nature's complexity and unpredictability, over millennia, the housing trajectory has increasingly prioritized sedentary behaviors, predictability, and comfort at the expense of cognitive stimulation. Modern life stress, mental health issues, and cognitive decline are markers of a poor environment. The pandemic lockdown has implicitly exposed that we need better houses for our brains. This paper goes back in time, navigating the cross-cultural evolution of environmental complexity to escape the contemporary dead end for the human brain that needs to evolve further. The paper advocates for a paradigm shift in housing design, emphasizing the need to foster neuroplasticity rather than constrain it. By reconceptualizing houses as architects of our brains, architecture becomes an independent variable embedding what the brain needs rather than embodying what the brain wants.
