You’re 10. The lunch bell just rang. The epic and thrilling sport of kickball is about to begin. Now it’s time to pick teams. Today you’re relived to get picked in the middle. The other kids are getting picked. Now there’s just two left. You look out with sadness at the last two schmucks. One of them will end up getting picked second-to-last and one sorry kid will have to endure the gut-wrenching feeling of being the only one on either team that didn’t get picked at all. The second-to-last kid is picked. You look out at the face of that last pitiful kid. How do you feel?
If you answered, “Hey! I was that last kid!” you make a
really good point. Before we look at empathy, let’s take a quick look at our
own emotional pain. Researchers set up a virtual playground where participants
were playing the videogame “cyberball” while in a brain scanner (fMRI). And
then, in the equivalent of the playground, two of the players rejected the participant.
What happened? Ouch. What did the researchers see? A part deep in the brain
right between the temples called the Anterior Cingulate Cortex (ACC) burned
bright with activity. They asked the participants how bad it was, and they
found that the more distress they felt, the brighter the ACC burned. Getting
picked last for kickball is a terrible thing.
But what’s also terrible is watching someone get picked last. The experiment was repeated, but
this time the participant watched while another player got rejected. What
happened this time? Ouch again. Again, the ACC burned bright. Watching someone else
get picked last is also a terrible thing.
It turns out that the ACC seems to be important for feeling
any kind of pain. It lights up when you stub your toe or when you watch someone
else stub their toe; it lights up when you get dumped, or when you hear about
your friend getting dumped. One group even looked at patients who cannot, for
neurological reasons, feel physical pain. They found that even these patients
were still able to share a pain they never felt; their ACC was active when
watching others experience physical pain.
This might lead you to think that the ACC was important in
making people altruistic. You may think: the worse you feel about someone
else’s situation, the more likely you are to help. The more pathetic-looking
they make the African orphan on the commercial, the more likely you’ll donate
money. But it’s false. Even though it seems to be an indicator of pain, it
doesn’t seem that pain produces altruistic action. In the study of the
cyberball watchers, the participants got a chance to write an email to the
rejected player, and this was then rated by how helpful and comforting it was.
Changes in ACC didn’t predict nice emails. In another study of people looking
at pictures of hurricane victims and considering donating money, they found the
same thing: ACC was active but didn’t predict generosity.
What did? A part of the brain between the temples near the
top of the head (dmPFC). The more dmPFC activity, the more helpful the emails
to the rejected cyberball players, and the more money was committed to the
hurricane victims. Why?
To answer that, we need another experiment! This time,
researchers tested a very strange hypothesis: the most selfless people were
actually being selfish. In other words, they tested whether people’s generosity
was because they felt bad for people in a bad situation, or whether it was
because they considered themselves “one” with the others. Oneness, “reflects a
sense of interpersonal unity, wherein the conceptions of self and other are not
distinct but are merged to some degree.” They asked people how they would help
various kinds of people (from strangers to family), in various situations (from
a phone call to helping their orphaned kids) and found that the empathic
concern was only important insofar as the people considered themselves one with
the other person. Their altruism was driven by their oneness, not their
empathy.
So what about our friend, the dmPFC? It turns out that it’s
more active when we’re making evaluations about others, particularly when we’re
considering others as a part of ourselves, a part of our group.
Conclusion
It seems that the emerging story is that empathy is an
important human capacity. You can look at a person in pain, feel bad for him,
and keep on moving. In fact, it doesn’t seem to matter how much it actually hurts
you to see another in pain. So long as you think of the person as ‘him,’ you’ll
probably walk on by (probably crossing to the other side of the road while
you’re at it). But the more that you think of the other person as ‘me,’ the
more likely you are to let your empathy drive you to action. Jesus may have
been speaking quite literally when He said, “Love thy neighbor as thyself.”

Professor Plumb was in the library, but did he actually
commit the murder? We see a provocative correlation, a brain region that lights
up when you’re about to do good, that same region lighting up when you consider
people part of your group, and the observation that feeling “oneness” with
others lines up with altruistic action. All the pieces are in line for it to be
true, but we don’t know for sure. That is to say, the above goes into the
category of “speculative hypothesis.” All these observations might be explained
by a third factor. Or it might turn out that some of these observations are
actually false. Or an hundred other things. That’s the problem (and the fun) of
speculation. So long as the speculation is backed up with a firm Theology (i.e.
that we ought to obey Jesus regardless of whether there are discovered neural
pathways to support His advice), it’s all in good fun.
