…the web, you can analyze usage data for your product and compare different interfaces in A/B tests. This is sometimes called “data-driven design”, but I prefer to think of it as data-informed design — the designer is still driving, not the data.
In 2004, a neuroscientist named Tania Singer and her colleagues published an important research study that showed how pain-receptive regions in the brain activate when we feel empathy with someone else’s pain. Since their paper came out, Singer has called empathy a “precursor to compassion,” differentiating these two words we too often use interchangeably. In an interview with the Cognitive Neuroscience Society, Singer explained the difference: “When I empathize with the suffering of others…I am suffering myself…In contrast, if we feel compassion for someone else’s suffering, we…feel concern — a feeling of love and warmth — and we can develop a strong motivation to help the other.”
