In spite of Alfred's gregarious personality, he does not have much luck on dates: objects of his affection tend to be put off by his insistently probing questions, mistakenly conflating his desire for luculent explanations with an unattractively manichean refusal to accept nuance or subtlety.

I cannot fathom how people believe in the utility of the Myers-Briggs Type Indicator, how a conflation of points on four ill-defined spectra is supposed to provide a luculent insight into one's personality; it is perfectly obvious that the only meaningful difference between people is a manichean division between the gregarious and the loners.

My gregarious nature made me believe that combining our dinner parties would lead to a better time being had by all (not to mention less cooking for me), but Harriet (who tends to conflate intelligence with moral excellence) declined with a luculent tirade on her manichean theory of socializing: to wit, my friends are dull and shallow and she'd sooner invite her friends to eat with axe murderers.

My elderly neighbors, while still luculent, have become curmudgeonly and have taken a manichean view of the neighborhood: they conflate the harmless but gregarious teenagers on our street with a gang of hoodlums who threaten their peaceful porch. (by neatlynoted)

Hoping to avoid a date with another wishy-washy relativist who prefers weak beer and the conflation of good and evil, I put "manichean" in my eharmony profile, but it was no use: my date last night turned out to be a gregarious evangelist for agnosticism, who wanted me neither for my ideals nor my body, but merely for the opportunity to refine and increase the luculence of his argument against certainty.

Having serious trouble getting along with her boyfriend Yang despite her gregarious nature, Yin finally broke down and sought Arthanari's advice, who recommended that that the couple be more open to a conflation of roles, and luculently explained how a manichean view of the relationship was not good for the balance of the universe.
