Why most people are right handed but left eyed

Whether you’re left, right or ambidextrous, “handedness” is part of our identity. But a lot of people don’t realise that we have other biases too and they are not unique to humans. My colleagues and I have published a new study that shows aligning our biases in the same way as other people may have social benefits.

Across different cultures, human populations have high levels of right-handedness (around 90%). We also have a strong population bias in how we recognise faces and their emotions.
