The World Until Yesterday, by Jared Diamond.

coverwuyPre-industrial societies are very different from ours. Some of them kill grandparents when they get to a certain age. Individuals are often fluent in ten or more languages. They feast when food is plentiful, but are happy to go without for several days if there is nothing to eat.

Until a few thousand years ago, all humans lived in this way. It is what we evolved to do. This book is a fascinating account of Jared Diamond’s lifetime of observation of pre-industrial people from around the world. It is long, but packed with packed with intriguing stories from tribal societies.

Not surprisingly, Jared Diamond thinks that we have a lot to learn from these people.

Right Hand, Left Hand, by Chris McManus

512yxI6NxbLThe left hemisphere of the brain is “logical”, and the right is “emotional”, yes? Left handed people are more creative? Right handed people more logical? These are the kind of pseudo-scientific factoids that give psychology a bad name with other scientists. Like many lazy oversimplifications, there is a grain of truth at the core of them. Proper psychological science is about using observation and experiment to get to the bottom of the matter, and this book reviews what we actually know about lateralisation of function in the human brain.

It is really readable. It ranges from psychology to anthropology, molecular biology to astronomy, and cultural studies to anecdote. It has won loads of prizes, is great fun to read, and frankly is absolutely fascinating.

If you’re just interested in the psychology then perhaps start with chapter 8, but in fact I would just start at the beginning because you’re probably going to end up reading the whole thing anyway!

Snog, marry, avoid? by Mairi Mcleod.

Men like younger women, women like richer men, right? Yes, but the picture is more nuanced than that. This New Scientist article unpicks some recent research into the details of sexual attraction.

“Women who are grossed out by blood and faeces prefer more masculine faces.”

“As the gender pay gap decreases in the West, attitudes to promiscuity are relaxing.”
