Humankind’s basic problem-solving apparatus – the brain – isn’t up to modern challenges. Do biology and evolution keep people from fixing the world?
Sociobiologist Rebecca D. Costa asserts that modern challenges, like society’s rapidly snowballing complexity, are outstripping humankind’s evolutionary cognitive abilities. One symptom of this problem is that people are addressing the world’s most pressing issues by wielding rigid, misguided beliefs, or “supermemes.” Costa, who takes her title from an 1865 history of the Boston police, warns that the modern world could go the way of past great civilizations unless people improve their mental functioning. She shows how strategies that helped humans survive in antiquity – like heavy calorie consumption – have become modern problems. Now, humanity can’t wait any longer for evolution to bail it out. People must foster the brain’s latent power of insight to tap into discovery and innovation without waiting for crises to force their thinking to expand. Costa is engaging and persuasive, despite her motivational speaker’s tone. Her message includes advice on how improving your personal brain fitness could also improve society’s future. While always politically neutral, getAbstract recommends her original insights to policy makers, executives, HR experts, scientists and readers seeking fresh solutions.
In this summary, you will learn
- How global problems are outpacing people’s evolutionary thinking capacity,
- Which accepted beliefs or “supermemes” threaten society’s ability to solve its problems, and
- How people can bridge their cognitive gaps and nourish mental function.
