light-minded
Not seriously focused
Light-minded describes someone frivolous, lacking seriousness, or easily distracted by trivial matters.
The term carries a faintly disapproving tone, suggesting someone who doesn't give weighty subjects their due consideration: She dismissed him as light-minded and unsuited for the responsibility.
The word is somewhat old-fashioned, more common in earlier literature than contemporary speech.
