Abstract
Janusian thinking is the capacity to conceive and use two or more opposite or contradictory ideas, concepts, or images simultaneously during creative work — a secondary-process move that produces novelty through structural opposition, not thesis–antithesis synthesis.

Key findings
- Simultaneous opposition — Creators hold logical antitheses in one frame at once — positing an opposite as of equal truth value to a prior notion (Rothenberg, 1971).
- Not dialectic or ambivalence — Sequential thesis–antithesis–synthesis and alternating conscious feelings are different processes — Janusian = cognitive co-presence during directed creative work.
Application
When you need a both/and breakthrough, ask what opposite must remain true at the same time for the idea to work — not what compromise closes the tension fastest.
When the same move appears in scientific breakthrough framing, see Rothenberg 1983 — Janusian process in science.
