Thanks to Steve for letting me know about a study that confirms what seems intuitively obvious.
People become more politically liberal immediately after practising a spiritual exercise such as meditation, researchers at the University of Toronto have found.
"There's great overlap between religious beliefs and political orientations," says one of the study authors, Jordan Peterson of U of T's Department of Psychology. "We found that religious individuals tend to be more conservative and spiritual people tend to be more liberal.
"Inducing a spiritual experience through a guided meditation exercise led both liberals and conservatives to endorse more liberal political attitudes."
Here's a few other excerpts from the newspaper story.
The researchers confirmed that religiousness was associated with political conservatism, while spirituality was associated with political liberalism. These associations were in turn due to the common values underlying these orientations: conservatism and religiousness both emphasize the importance of tradition, while liberalism and spirituality both emphasize the importance of equality and social harmony.
..."Spiritual experiences seem to make people feel more of a connection with others," says Hirsh. "The boundaries we normally maintain between ourselves and the world tend to dissolve during spiritual experiences. These feelings of self-transcendence make it easier to recognize that we are all part of the same system, promoting an inclusive and egalitarian mindset."
