Grief and science share an awkward secret: both require you to let go of something you were sure was true. The Yoruba philosophical tradition speaks of *àṣà* — inherited patterns of knowing that shape what a community considers real — and what's striking is how it frames the shedding of those patterns not as loss but as a form of moral maturity. Scientists often describe the moment a cherished theory collapses not as intellectual defeat but as something closer to mourning: the lab notebooks, the years, the identity built around being right. Psychologist Paul Rozin's research on what he called 'the tragedy of good understanding' found that experts feel genuine grief when a clean, elegant explanation gets complicated by new evidence. The practical upshot: when new data makes you feel strangely sad rather than merely puzzled, that emotional signal is worth attending to. It usually means something real is being released — not just a hypothesis, but a piece of how you've understood yourself.

What conclusion in your current work would genuinely hurt to abandon — and what has that attachment already cost you?
