O teste A\/B \u00e9 supostamente a forma racional de tomar decis\u00f5es sobre produtos: lan\u00e7ar duas variantes, avaliar qual tem melhor desempenho e ficar com a vencedora. Parece ci\u00eancia. Mas, muitas vezes, n\u00e3o \u00e9.<\/p>\n

Os problemas com que nos depar\u00e1vamos constantemente<\/h2>\n

A maioria dos testes A\/B \u00e0 nossa escala tem um poder estat\u00edstico demasiado reduzido para serem significativos. Os testes que s\u00e3o<\/em> funcionam durante tanto tempo que algo mais na aplica\u00e7\u00e3o ou no mundo muda por baixo delas, contaminando o resultado. E a m\u00e9trica que est\u00e1s a medir quase nunca \u00e9 aquela com a qual realmente te preocupas \u2014 otimizas para cliques porque os cliques s\u00e3o quantific\u00e1veis, e o que realmente querias (confian\u00e7a, reten\u00e7\u00e3o, prefer\u00eancias) desvia-se numa dire\u00e7\u00e3o que nunca mediste.<\/p>\n

O que fazemos, em vez disso<\/h2>\n

Concebemos duas op\u00e7\u00f5es, escolhemos a que melhor reflete a ess\u00eancia da aplica\u00e7\u00e3o, lan\u00e7amo-la com confian\u00e7a e ouvimos atentamente o que as pr\u00f3ximas seis semanas de coment\u00e1rios e pedidos de apoio nos revelarem. Estamos dispostos a errar, por vezes, em troca de n\u00e3o termos de ter sempre a certeza estat\u00edstica.<\/p>\n
