The idea at the center of this page is borrowed, so the credit comes first. Psychologist Mark H. Davis built the Interpersonal Reactivity Index on the premise that empathy is a set of related but separate tendencies rather than a single trait, and he measured four of them apart: perspective taking, empathic concern, personal distress and fantasy. The Empathy Prism takes only that starting point. Its eight moments were written for this page, none of the index's statements appear in it, it has never been validated as a measure, and neither Davis nor Eckerd College is connected to it or has endorsed it.

Three colors, not one number

Most empathy quizzes add every answer into one score, which hides the most interesting part. This one splits each moment three ways.

• Understanding is working out what someone feels and why. Researchers call it cognitive empathy, perspective taking or mentalizing.
• Feeling with is catching a share of the feeling yourself, like the heaviness that arrives when a friend's voice goes quiet on the phone. This is affective, or emotional, empathy.
• Wanting to help is the warm pull to do something about it. Davis called it empathic concern; you will also see it called compassionate empathy.

The first two are named as different capacities in the research itself. Tania Singer and Olga Klimecki's short overview separates inferring what is on another person's mind from sharing what they feel, and gives each its own vocabulary. The third can drift from both. You can read a coworker's embarrassment perfectly and feel very little, or carry a stranger's sadness for three stops and never think to pass a tissue across the aisle. One total would average those differences away. Three beams keep them in view.

How the prism works

The eight moments come in four kinds, two of each: someone close to you, a stranger, someone you are at odds with, and a moment when you are rushed. Each moment has three lines, one per color, and you mark each on a four-step scale from not really to very much. There is nothing to type until the very end, and even there a suggestion will do.

A moment sends its light through the glass only when all three of its lines are marked, so the beams always hold finished moments and the count beneath them means exactly what it says. Once all eight are through, you hold them up to the light and the reading opens: which colors your answers lean toward, a word for each beam, and the kind of moment where your marks ran lowest overall. That last part comes with one practice written for that kind of moment and a line for when you plan to try it.

Nothing is locked. Go back to any moment, change a mark, and the reading follows, including which kind of moment is quietest.

What the evidence does and does not say

The most useful finding here is that empathy is not a fixed quantity you either carry or lack. Jamil Zaki's review of the research argues that it shifts with the person and the situation, because people turn it up or down depending on what engaging would cost them, from shared suffering to money to losing ground in a competition. That is why this page sorts its moments by kind: the same person can be tender with a sister and closed off toward a stranger in line.

Hurry is one of the plainest examples on record. In a classic experiment, seminary students told they were running late were far less likely to stop for a stranger in obvious distress than students with time to spare, and how religious they were did not predict who stopped. If your quiet kind of moment turns out to be the rushed one, you are in very large company.

Now for what the prism cannot do. It records how you imagine you would respond, and imagined responses can run kinder or colder than real ones. Eight short scenes are a thin slice of a life. There are no norms behind the words bright, steady, soft and faint; they place your own marks on the scale, not you against anyone else. It is not a screening tool and says nothing clinical. A quiet beam is somewhere to practice, not a finding about your character.

When to use it

Take it on a calm evening after a week full of people, and answer the way you would on an ordinary day rather than your best one. Give the practice a few weeks, then start over and see whether the quiet kind of moment has moved.

If understanding turns out to be your quietest color, the Perspective Journal replays one real moment from your side and then from theirs. If wanting to help runs low, the Loving-Kindness Circle sends goodwill outward in widening rings, from yourself to people you barely know. And if you often sense that someone is upset without finding the word for it, the Feelings and Needs Card lends a vocabulary of feelings and the needs underneath them.
