The researchers emphasize that damage to this brain network does not guarantee that a person will develop fundamentalist beliefs, nor does it imply that individuals with strong religious convictions have brain damage. Instead, the findings point to the possibility that certain brain networks influence how people process beliefs and how flexible or rigid their thinking becomes, especially in the context of religion.

The nature vs nurture debate is on a scale. While twins might share the same predilection for religiosity due to their genetics, upbringing plays a huge part as well, which is why Squid’s researcher is careful to qualify the answer with ‘in general’. There’s also the concept of neuroplasticity which means damage to the relevant networks does not necessarily doom one to permanent deficits in the associated neural functions. The brain can often recover or adapt post injury.

Considering this, the research is useful in that it allows professionals to predict areas in a patient’s behaviour that might need therapies to return to normal, guidance to set expectations, or as an indicator of damage should sudden related and unexplained behaviour changes occur. It ofc also adds to the body of evidence that associates these parts of the brains with various functions.

More to your comment: You’re right. This needs to be considered carefully because there is a long troubled history with labels in neuropsychology becoming misnomers and insults. For example the terms ‘moron’ and ‘idiot’ used to be an official diagnosis once up on a time.
