It might seem obvious, but this part is extremely important and can be very difficult to live by because it encourages (healthy) disagreement and conflict. "Strong opinions, weakly held" is explicitly _not_ about giving in to a majority opinion or because the opinion is coming from a position of higher authority. It's essentially the scientific method. It does not mean you should agree with other peoples' opinions just because they said it louder and/or more often than you did.
I've witnessed senior engineers and managers misunderstand this mantra and (mis)use it to punish ICs who disagreed with ideas of other more/tenured engineers but lacked evidence for being "better".
If you intend to use this framework as a value in your organisation, make sure you and everybody else understand what it means (_especially_ your engineering managers).
