Research from psychology and neuroscience says people make better decisions with their emotions, so we should trust our emotions over our experience and intellect. So stop being so darn logical when it comes to God.
Reality check: that's a distortion of the research, which generally says something along the lines of, "emotion and cognition are more intertwined than we used to think." In contrast, the believer is acting as though emotions and logic are totally separate and emotion has been found to be superior.
The main research usually cited (though not in the latest case I'm responding to) is Antonio Damasio's Somatic Marker Hypothesis. According to this hypothesis, when we make decisions, our brain creates a representation of the bodily state we would feel if we went ahead with the alternative under consideration. I.e., you are deciding whether you want to stick your hand in a fire, and your brain creates an affectively-laden representation of how you would feel, and you pull your hand back. Thus, decision-making and emotional cognition are intertwined, and can't be pulled apart neatly into logic vs. emotions.
The more recent example I saw cited neuroscience research, which suggests that emotionally-laden stimuli are treated as more salient by visual and attentional systems. (In other words, emotional things, like things that could hurt you, get higher priority in being processed by your brain.)
Does any of that mean we should "trust our emotions over logic?" Not really. It means that even when we think we are thinking logically, there may be emotional representations at play that guide our judgments. Or, that emotional overtones may determine what our brain finds important enough to attend to. Now, there is indeed research that suggests that in some cases a gut decision will be better than a deliberated decision, but that's about conscious vs. unconscious processing, not emotion vs. reason.
But we already knew the research couldn't have meant what the believers claim it does. Let's consider what it would mean if we should literally trust our emotions over experience and logic:
Fred is afraid of getting a shot, and so he refuses to do so. His doctor tries to persuade him that he needs the vaccine before he goes overseas, but Fred insists that he is better off trusting his emotions, which tell him not to get the shot.Arthur feels a special high around his cult leader. Arthur's parents try to show him the facts about the leader's scamming history, but Arthur insists on following his emotions and giving up all his money to the cult.
Does anyone actually intend this? Of course not--they want it only to apply when it comes to emotions regarding religion. But it's important to note how the research is being distorted in these scenarios and the religion scenario: part of the reason these scenarios are bogus is that Fred also has a "somatic marker" of what it would be like to get malaria and die, which will also influence his decisions. That's the point--the research says emotions and logic are often intertwined on both sides of a decision, whereas the believer is acting as though logic and emotion are separate and emotion has been found to be superior. This is just plain wrong.
