Empathy

So, I see that Simon Baron-Cohen’s empathy test is making the rounds on Tumblr. That provides me with an opportunity to talk about a common misunderstanding about empathy.

The test, like most people’s thinking, is confusing at least two different phenomena that fall under the umbrella of “empathy”. Consider this: it has been said about both autists (high- and low-functioning) and psychopaths that their central characteristic is a lack of empathy. The stereotypical autist is a person doesn’t hurt a fly, if only because he lacks the social compass needed to do it; the stereotypical psychopath’s social compass is so well-developed that he effortlessly manipulates people for his own ends and purposes, regardless of the potential harm to the humans that become his instruments. Intuitively, it seems as if these two kinds of people shouldn’t be called variations on the same theme (lack of empathy).

And indeed, such is the case. There are at least two different concepts that are easily conflated under the empathy term. One is called cognitive empathy, which also commonly goes by the name “Theory of Mind (ToM)”. It is, roughly, the ability to predict and form a mental model of other people’s emotional state, their intentions and desires on the basis of nonverbal cues. Basically, social skills. Being able to tell when your conversation partner is bored by what you’re saying, for instance. Understanding the emotional state of someone by looking at their body language. Reading body language, tone of voice, context, and so on. This skill is present in psycopaths (unless they happen to have some other abnormality) and weak or not present at all in autistics and folks with nonverbal learning disabilities.

The other kind of empathy is affective empathy. If you understand that someone is being treated cruelly, if they are hurt and you feel sympathy for them, that is a sign of affective empathy. It has nothing to do with acquaring information about people’s emotional states, it is rather about how this knowledge (if/when you acquire it) affects you (if at all). This kind of empathy is weakened or nonexistent in psycopaths. If they are aware that they are hurting other people, that knowledge will often not move them to sympathy or regret. This kind of empathy may, in fact, be better than average in autistics. The abstract of one paper reads:

We administered the Interpersonal Reactivity Index (IRI), a multi-dimensional measure of empathy, and the Strange Stories test to 21 adults with AS [Asperger Syndrome] and 21 matched controls. Our data show that while the AS group scored lower on the measures of cognitive empathy and theory of mind, they were no different from controls on one affective empathy scale of the IRI (empathic concern), and scored higher than controls on the other (personal distress).

There is clearly a need to nuance here. We could go even further. ToM suggests that the defining characteristic of autists may the inability to form a working ToM — a mental map of other people’s emotional state, intents and so on. But then we can nuance this further by asking: is this due to an inability to form a Theory of (someone else’s) Mind, or is it due to the inability to acquire the information necessary to do this due to an inability to read nonverbal cues? Some suggest that autists in fact lack the conceptual machinery to form a working ToM, even if all the information they would need to do so was presented for them.

One common test to show this is to present the following scenario: let a child observe the following:

  1. There is a room in which an object (e.g., a doll or a ball) is placed, while another person is watching and clearly (this is important) sees where the object is placed.
  2. The person leaves the room.
  3. The object is hidden somewhere else. The person who left the room clearly does not know where the object was hidden, or even that it was hidden.

Then ask the child where the person that saw the object be placed, but did not see it be hidden will look. Supposedly, all children over a given age (including children with Down’s, for instance) will say that the person will look where the object was originally placed, which is the correct answer, but autistic children will be a lot older before they grasp this, and will say that the person will look where the child saw it be hidden; and this is due to a failure to mentally differentiate between the child’s knowledge and another person’s knowledge — to form a working ToM. So perhaps there are people who lack the ability to form Theories of Mind given all information they might need, and others that can form working ToMs but are unable to extract the necessary information by reading body language.

Fascinating stuff, people. But the point with this post was to illustrate the difference between different kinds of empathy, and not do so in a wishy-washy New Age kind of way. This is especially important since empathy is often not used in a value neutral way: often, to say that such-and-such is empathic implies that they are a good person, while saying that such-and-such lacks empathy often implies that they are akin to a psychopath.

Seriously, people. Grow up. Who would want to buy anything from someone who doesn’t display any emotional maturity?

Thought:

There is an Alcoholics Anonymous, but what the world really needs is Celebrities Anonymous. Of course, it wouldn’t work because it’s essentially contradictory: celebrities are people who simply can’t show up to a meeting and expect not to be recognized. But the problem is real: the world is full of celebrities and wannabe celebrities who are addicted to a drug that is not recognized as a drug, namely attention. To get this drug, they do just as much stupid shit as alcoholics and junkies; the effects of overusing this drug are just as severe as those of alcoholism.

There were always people who were addicted to attention, but the current culture combined with modern technology makes it that much easier to indulge.

I wonder how long it will take before addiction to this dangerous drug will be recognized as an illness in the same way addiction to, say, narcotics is starting to be seen. Actually, I wonder how many celebrities (who let fame get to their head) and wannabe celebrities (who let the desire for fame get to their head) would qualify for currently recognized disorders such as Narcissistic personality disorder or Histrionic personality disorder. Since I despise amateur psychologists who employ their faulty understanding of what is already an inexact science in an amateurish way, I won’t attempt to actually diagnose any celebrities here, but many of them sure display signs — as do many of those who devote their lives to becoming famous.

Aww. Let’s all be friends. Aww. Let’s all be friends.

“So what will you do if string theory is wrong?”

Some string theorists are so reluctant to give up their pet theory that proving it to be completely wrong as a description of the universe isn’t enough for them to abandon it — they’re not even prepared to make the theory a part of mathematics:

So even if someone shows that the universe cannot be based on string theory, I suspect that people will continue to work on it. It might no longer be considered physics, nor will mathematicians consider it to be pure mathematics…

Whether or not string theory describes nature, there is no doubt that we have stumbled upon an exceptionally huge and elegant structure which might be very difficult to abandon. The formation of a new science or discipline is something that happens continually. For example, most statisticians do not consider themselves mathematicians. In many academic institutions departments of mathematics now call themselves “mathematics and statistics.” Some have already detached into separate departments of statistics. Perhaps the future holds a similar fate for the unphysical as well as not-so-purely-mathematical new science of string theory.

Peter Woit is none too happy:

The argument Emam is making reflects in somewhat extreme form a prevalent opinion among string theorists, that the failure of hopes for the theory, even if real, is not something that requires them to change what they are doing. This attitude is all too likely to lead to disaster.

Lots of Animals Learn, but Smarter Isn’t Better

Apparently, learning isn’t always such a good idea, evolutionarily speaking.

The day the music died

The one you purchased from MSN Music, that is. And if you were smart, you didn’t. I’m guessing you didn’t. This only affects the clueless, which is kind of sad.

… frankly I’m tired of being right all the time. It was fun for a while, but now it’s just depressing.

Why made a Ruby-bytecode-to-Python-bytecode translator, and a Python-bytecode-to-Python-disassembler. That’s pretty cool. (Thanks strelau)

The Devil's Dictionary

Ambrose Bierce’s satirical redefinitions of English words are as relevant as ever, in that they nail illusions and political double-speak better than most of their imitators. They are also often funny. The dictionary contains definitions such as:

REALLY, adv. Apparently.

CYNIC, n. A blackguard whose faulty vision sees things as they are, not as they ought to be. Hence the custom among the Scythians of plucking out a cynic’s eyes to improve his vision.

SELF-EVIDENT, adj. Evident to one’s self and to nobody else.

DEBT, n. An ingenious substitute for the chain and whip of the slave- driver.

JUSTICE, n. A commodity which is a more or less adulterated condition the State sells to the citizen as a reward for his allegiance, taxes and personal service.

MISS, n. The title with which we brand unmarried women to indicate that they are in the market. Miss, Missis (Mrs.) and Mister (Mr.) are the three most distinctly disagreeable words in the language, in sound and sense. Two are corruptions of Mistress, the other of Master. In the general abolition of social titles in this our country they miraculously escaped to plague us. If we must have them let us be consistent and give one to the unmarried man. I venture to suggest Mush, abbreviated to Mh.

And many more besides. Wikipedia has some more highlights. I can’t resist adding a few more:

MOLECULE, n. The ultimate, indivisible unit of matter. It is distinguished from the corpuscle, also the ultimate, indivisible unit of matter, by a closer resemblance to the atom, also the ultimate, indivisible unit of matter. Three great scientific theories of the structure of the universe are the molecular, the corpuscular and the atomic. A fourth affirms, with Haeckel, the condensation of precipitation of matter from ether — whose existence is proved by the condensation of precipitation. The present trend of scientific thought is toward the theory of ions. The ion differs from the molecule, the corpuscle and the atom in that it is an ion. A fifth theory is held by idiots, but it is doubtful if they know any more about the matter than the others.

MONAD, n. The ultimate, indivisible unit of matter. (See Molecule.) According to Leibnitz, as nearly as he seems willing to be understood, the monad has body without bulk, and mind without manifestation — Leibnitz knows him by the innate power of considering. He has founded upon him a theory of the universe, which the creature bears without resentment, for the monad is a gentlmean. Small as he is, the monad contains all the powers and possibilities needful to his evolution into a German philosopher of the first class — altogether a very capable little fellow. He is not to be confounded with the microbe, or bacillus; by its inability to discern him, a good microscope shows him to be of an entirely distinct species.

I’m inclined to agree with Marco that these auto-generated lists are useless (I don’t care what music you’ve been listening to the most lately; if I did, I could go to Last.fm myself!). But this is double useless.
