A recent article in The Economist magazine examines a bunch of scientific papers about online dating in an attempt to figure out if any of those fancy matching algorithms are better than old-fashioned matchmakers like your grandmother. Or even if simply all that choice — and all those checkboxes! — improves your odds of finding love. Turns out there’s very little data to support either theory — and what data there is (hi, Malcolm Gladwell) suggests that too much choice means people (a) make bad decisions and (b) feel less satisfied with their ultimate choice. Oh, yeah, and related research shows that, yes, people with similar personalities tend to have happier relationships — but by the not-exactly-earthshaking margin of 0.5%. In other words, if you want to have a 0.5% better shot at happiness, make sure you go online to find someone who checks all the same boxes as you.
