You can predict outcomes from seconds of exposure, sometimes with unsettling precision. First impressions from speed dating forecast 70% accuracy for six month relationship success, while 80% hiring outcomes hinge on thin slicing from just 30 second clips. We also look at where it breaks down, like a 25% cross cultural swing in perceived facial competence and how interrater reliability averages ICC 0.52 across traits.
