A study published in the journal Behavioural Neuroscience suggests variations in the COMT gene may account for different reactions to horror films. Some people scream while others - for example, me - laugh (hat tip to Agent Bedhead).
The scientists found that those carrying two copies of it were significantly more startled by frightening images than others. By contrast, those who had one copy of the gene and one copy of another version were able to keep their emotions in check far more readily.
I am going to go out on a limb here. Many people react to disturbing images by blaming themselves or those nearest to them for the horror; by attempting to make the images stop by denial, conspiracy theory or surrender.
And some of us develop a cold rage and a determination to make certain nothing like it ever happens again. People with our genetic variant are called "sane".
