Science doesn’t back that up, really. According to pain researchers, your brain can experience hurt on a different scale than the person sitting next to you. Simply put, pain is largely subjective.

Obviously there are a lot of factors at play: where you get hit, what kind of gun, and whether you’re expecting to feel the hot kiss of a speeding bullet. Zhuo said he’s found that anxiety levels affect how people feel pain. The more uptight or scared you are, the more pain you’re going to feel. So assuming you’re caught off-guard, and shot in a place that won’t kill you, Zhuo placed “Getting shot” between 2 and 3 on the Painometer.

In Diatchenko’s research, she routinely asks subjects to rate their most painful experiences. For women, the highest rating is almost always childbirth. “In pain research, if a woman is asked ‘What is pain?’10 is childbirth,” she said. So it gets 10 on the Painometer.

Min Zhuo hasn’t felt the sting of a rubber bullet, either. But asked to place it on the pain scale, the Canada Research Chair in pain and cognition and medical professor at the University of Toronto said it would fall between 3 and 4. “They are not going to penetrate your tissue … It could cause more damage in a wider area.”

Having experienced this himself, Zhuo can attest that it hurts, but he said the main source of that pain is the fear and anxiety that surrounds the male predilection to safeguard the family jewels. “It’s more of the fear component,” he said, rating the pain at 6 on the scale. “We have very clear evidence that those anxious people, they’re going to perceive pain much, much longer and much more.”

Zhuo said he was hit with a soccer ball in the face once, and it hurt real badly. A baseball in the face? That’s got to be intense. “Our face sensory nerves are very close to the brain, so it can be very painful.” Painful enough to warrant a 7 or 8 on the scale.

Luda Diatchenko has never been shot with a rubber bullet. She’s never spoken with someone who knows how much they hurt.

It can be very painful and it can create damage,” she said. “It can be the beginning of chronic pain.”
