Is Science A Belief? Is Religion A Science? Recent Research

The researchers “used functional magnetic resonance imaging (fMRI) to study the brains of 14 adults while they judged written statements to be “true” (belief), “false” (disbelief), or “undecidable” (uncertainty). To characterize belief, disbelief, and uncertainty in a content-independent manner, we included statements from a wide range of categories: autobiographical, mathematical, geographical, religious, ethical, semantic, and factual.” […]

There was a significant difference in the response speed for statements that were true compared to those that were false or undecidable. There was no significant difference between the reaction times of these latter two categories. Thus, “Several psychological studies appear to support Spinoza’s conjecture that the mere comprehension of a statement entails the tacit acceptance of its being true, whereas disbelief requires a subsequent process of rejection. Understanding a proposition may be analogous to perceiving an object in physical space: We seem to accept appearances as reality until they prove otherwise. Our behavioral data support this hypothesis, insofar as subjects judged statements to be “true” more quickly than they judged them to be “false” or “undecidable”.”

Looking at the brain scans, the images showed a distinct increase in activity in the ventromedial prefrontal cortex (VMPFC) for statements of belief versus disbelief. This VMPFC appears to be involved in reasoning tasks that have a high emotional salience, including modulating behaviour in response to changing rewards, selecting goal-based actions and, it seems, in on-going reality monitoring. Thus if our reality is the sum of true propositions then each manifestation of such propositions gets a positive emotional boost, as if to verify that it still holds true. Damage to the VMPFC has been associated with an inability to feel any moral consequences to planned actions as well as to confabulations, where reality-checking has seriously broken down. What was surprising was that this activity in the VMPFC was independent of the content of the propositions: mathematical propositions that were true showed the same signal as religious propositions that were deemed true by believers, as well as irreligious propositions deemed true by disbelievers. What we seem to be witnessing is part of the brain’s truth checking system, and that system is powered by emotions. […]
