Another example of such a belief is that "humans are inherently evil" which seems to have been planted in Western society by the concept of original sin. Interestingly the idea that sin was about our inherent badness didn't really arise until the struggle against Gnosticism [1] hundreds of years after Jesus died.
Now the belief is pervasive in secular society thanks to stories like "Lord of the Flies".
It's fascinating how even though we can call ourselves non religious we can still carry these beliefs around.
