Not necessarily a problem whenA strong opinion is also the strongest evidence-based position and the process still allows real challenge
Common false friendStrong opinions from experts are always the most efficient way to decide
Certain people dominate design outcomes regardless of preparation quality, domain fit, or opposing evidence.
Also observed<br>We are doing this because leadership likes the direction.<br>Nobody challenged the strongest voice in the room.
Likely reading<br>Weak decision process<br>Status-driven culture<br>Low safety for dissent
Not necessarily a problem when<br>A strong opinion is also the strongest evidence-based position and the process still allows real challenge

·Decision records
·Who gets to define trade-offs
Questions to ask<br>What evidence changed the decision?<br>Would the outcome be different if names were removed?<br>Who speaks least and why?

Anti-patterns when responding<br>Confusing confidence with correctness<br>Using seniority as a shortcut for decision quality
AI amplifies<br>AI-generated decks and summaries can arm dominant voices with polished but weakly grounded arguments.
AI masks<br>High-quality presentation can make shaky reasoning look rigorous.
AI synthesisThe winning argument is the best AI-polished one, not the best evidenced one.
