By being a cynical bastard about human society. In my Eberron game, the paladin is free to detect evil all the time. But experience has taught him that about 20% or so of people in society are evil, so detecting evil doesn't help that much. Especially since being evil is not a crime and most of the evil people he meets are productive members of society. Sometimes there are evil people whose goals match the party's and they help the PCs, and there are good people whose goals oppose the party's and they oppose them. Detecting evil just tells you someone's alignment. It tells you next to nothing about how the person will act in the given context.
On top of that, there's the whole issue of how imprecise the detect evil ability is. Not only can it detect non-evil people as evil (a LN cleric of a LE god detects as evil, for example), but it also doesn't tell you exactly how evil someone is. An 11th lvl commoner who lies and cheats and steals and beats his wife detects as more evil than a genocidal 9th lvl fighter who has killed thousands of innocent people with his own hands, both of whom detect as less evil than the 5th lvl cleric of Vecna whose primary focus is on discovering lost knowledge in the library archives.
No, detect evil is really not much good at revealing anything relevant about people.
