From https://bigthink.com/strange-maps/geopsychology-regional-personality-variation:
"A high degree of openness signals a willingness to try new things, as well as a higher awareness of one's own feelings and creative talents. Low openness signals seeking fulfillment through perseverance rather than euphoria and being pragmatic — or perhaps even dogmatic."
You can conduct personality tests in different geographic locations and see what personality types preponderate in the general population. Here's what the map looks like for the UK (with orange meaning positive and blue meaning negative):
The openness map is almost entirely blue, meaning that most British people have conservative attitudes regarding change and are practical rather than dreaming.
This is what the class system gave us.
