Being selective or not is a style. It's not a fundamental. The BABIP is not statistically any different on the first pitch than it is the fifth pitch. If a guy feels more comfortable hitting on the first pitch, then they should do so provided they're not hacking at just anything.
BABIP doesn't have much to do with it. BABIP only applies to balls hit in play.
When a batter is patient he can walk more. He can strike out less. He can perhaps homer more. None of those things are reflected in BABIP.
Patience, waiting for a pitch you can handle, is a fundamental part of hitting. Great ball strikers can succeed without it, but most mortals do better if they wait for a pitch they can handle.
