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.”
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.
In contrast, when the researchers analysed those false statements compared to either true or undecidable ones they found increased activity in the anterior insula (on both sides) and the left frontal operculum. Taken together, these regions are associated with judgements about taste, smell and pain. Statements that are untrue - basically lies - are experienced as unpleasant or downright disgusting. Yet again, what we think of as rational decisions are mediated by emotional responses. Good and bad are thereby associated with pleasure and pain. The lessons of the real world are replicated by the brain so that it simulates such real world responses when reacting to purely mental constructs, even to statements that appear quite abstract and unemotional. What is worrying to a rationalist is that the same emotional weight is given to supernatural statements as to natural statements.
Lastly, a quick look at the fMRI scans for those propositions that were undecidable compared to those that were either true or false. These showed a marked increase in activity in the anterior cingulate cortex (ACC) and a decreased signal in the caudate. The ACC is thought to be involved in processes of error detection and behavioural responses to cognitive conflicts. It is therefore not surprising that it should also be involved in questions of undecidability, some of which may be the unresolved conflict between truth and falsehood. Overall, what the research has uncovered, is that the brain seems to treat propositions and thoughts about propositions in very similar ways to other sensory inputs. Decisions taken about the truth of statements seem mediated by emotional responses, with truth and falsehood eliciting respective feelings of pleasure and pain. This appears to be independent of the content of the statements and applies equally to natural and supernatural claims. This is an important step forward in understanding the neurology of belief. It also suggests that our lexical distinction between knowledge and belief may be much finer than we expected. To the believer, the belief is knowledge, and the brain reinforces this through its pleasure circuits. The mutual incomprehension between religious believers and non-believers starts to make sense. But it also means that an individual's supposed rational internal dialogue is also subject to the same processes. A person's mental map of the universe may thus be deeply flawed and yet trying to change it is a painful process that few are willing to undergo – in some ways we are all addicted to our prejudices.
When comparing the brain activity when a subject was confronted with non-religious statements compared with religious ones we find a distinct increase in many areas of the left hemisphere - including the hippocampus - that are involved in memory and language retrieval. Not a great surprise here, but interesting finding is that the believers and non-believers showed increase brain activity in exactly the same areas when responding to negative, or blasphemous, statements about Christianity. Thus although the Christians responded negatively to such statements, and the non-believers positively, the same areas were involved. It is not clear if this is purely down to the non-believers being largely former Christians.
The 17th century philosopher, Benedict Spinoza, conjectured that the mere comprehension of a statement was tantamount to a tacit acceptance of it being true, whereas disbelief requires a further process of rejection. On reflection, this would seem to make sense in terms of pure processing speed. Somehow, a false statement needs retesting and opening up to a wider search to verify its falseness. This is most obvious in mathematical statements; “62 is perfectly divisible by 9” takes longer to process than “62 is perfectly divisible by 2.” The number of values of x for which the proposition “62 is perfectly divisible by x” is true is very small compared to those for which it is false. Whether the brain actually attempts a global search in the hope of finding each statement as true may well be worth further research.
However, the current research shows that it isn't just a matter of processing power but also an emotional reaction to questions of truth and falsehood. Truth is beautiful, whereas falsehood is painful. This negative emotional reaction to false propositions may be the cue for a further search to see if one's original judgement is wrong – there seems to be an emotional prize in this extra mental effort in that discovering a new truth brings with it a sense of satisfaction and joy. However, what we seem to be left with is a form of mental hedonism. Is that the end of the trail?
Heart to heat right here man.
Logan, you need to stop watching the "History Channel" and change it to like PBS or Discovery / Science, after a year of watching them, I invite you to come back here and discuss how modern science is fucking retarded.
I bet you also doubt we landed on the moon, Obama is a citizen, and JFK was shot by someone else. sheeesh at least get a cool conspiracy theory like that he US planned pearl harbor (look it up its wild)
Jesus iDunno and Logan fucked up this thread. Mattj come here and tell us how your grandfather didn't see the big bang, lets get back to some reasonable discussion.
A Thought Experiment
Here is a thought experiment I designed (if it already exists elsewhere in the literature please let me know). Can a person hold two religious faiths simultaneously? Can, for example, a devout Christian also be at the same time a devout Hindu? You can replace those two religions with any other two you may choose and do the same thought experiment. Syncretistic beliefs count as new faiths so that the intersections of all sets of religious faiths is empty. This is not the same as the intersection of propositions of beliefs as there are obviously some beliefs that overlap. This experiment is not about the statements people make about their faith but their state of mind and emotional state associated with their faith. My proposition is that it is not possible to be a devout believer in two different religious systems.
Now let's add science into the mix. Many religious apologists like to state that science is just another belief system and that therefore their religious system is on a par with science. This means, to them, that religious claims to truth are equivalent to scientific claims to truth. If this is true then we would expect that if we added science into our religious mix above that it would also create a new set with no intersections with other religions. But this is obviously false. Can, for example, a devout Christian also be a scientist? Absolutely! There seems to me to be no emotional reason as to why religious individuals cannot also be scientists. To return to Aquinas, his sacred doctrine is both a religion and a science but the two remain distinct. But Aquinas does not have equal faith in both realms; in a conflict situation religious faith wins. It is unfortunate that we have one word – belief – that seems to describe two different states. These two research papers, however, suggest that both science and religion are mediated by beliefs that are reinforced by emotional circuitry. Essentially, both atheists and Christians believe they are right because it makes them feel good. But these experiments were conducted on discrete propositions – there is still a difference between their default states.
Why don't we have ancient alien classes in school either? That's wrong and it would cause ignorance to not teach it. I think we should teach everything in school because if you believe something is true, it makes it testable science (albeit not necessarily true). Ergo all sciences should be taught in school, that way people can choose whether to believe in ancient aliens, medicine, godjesus, the matrix, nanobots or invisible space teapots. You're all just too stupid to understand. Get on my level.
PS: This thread is amazing.
who would have thought that posting a disparaging picture about autism would invoke such an inundation of further autism
If you hadn't noticed I already did. I'm not campaigning against evolution. All my argument was about was religion actually being a form of science and people somehow derived that I was anti-science from that. If given enough reign men of science can be just as bigoted and dogmatic as men of religion. To avoid a future like that people need to be trusted to know about all religions and sciences and to choose what to believe for themselves. The core of intolerance is ignorance and choosing to teach some things but not others only perpetuates it.
just because I take consideration things you don't agree with/don't understand doesn't make me a "moron"
Again, I'm an atheist and accept scientific theories to be widely true given the evidence we are given, so I'm not on a campaign to discredit science as a whole...
Every time I hear someone make a disparaging remark about autistics, I remember that they are the target audience for the Big Bang Theory and I feel a little better.
Just because we believe in evolution doesn't mean we are stupid enough to think anyone but George W. Bush did it.I have a feeling man of you are the same people that still believe freedom hating Muslims took down 3 World Trade Center buildings with 2 planes.. Rme.
I didn't call you a moron, but considering the utter uselessness of your position, I can see why people would. It's not a justification, but it seems to me that you should have known what kind of territory you'd be treading into by communicating a position like this in the way you did. You don't get to escape a double standard callout with another double standard callout. Your repeated claims of "this is the last time I'm bothering to talk about this" is no better than popemobile's gif.Fine that's fair. But then again, on the same coin, having a differing opinion from mine does not give you a right to call me a moron, so we are both equally guilty of labeling.
With all due respect, I didn't compare the information contained within the Bible with the information contained within a textbook. I compared blindly, without any personal investigation, accepting what the Bible says to blindly, without any personal investigation, accepting what any textbook says. How is that any different? How would it be any different to blindly accept what Carl Sagan has said, than to accept what Jesus has said?i'm really irked about mattj's analogy between people believing what a textbook tells them to be true, and the bible.
Well, you can't do much to close floodgates after they've been opened :(
