If you’ve made some new year's resolutions and you’re hoping for a ‘new year, new me’ this is the episode for you. This week, we’re finding out if it’s really possible to consciously improve our personalities (although Rick seems to think there’s no need to improve on perfection). We’re also examining the validity of personality tests, finding out whether it’s true to say that animals have ‘personalities’ and we’re exploring the fascinating developments by machine-learning AI in personality research! Special thanks to today’s expert, Dr Christian Jarrett. Hosted on Acast. See acast.com/privacy for more information.
