How to manage voting / balancing people (e.g. 60% want one thing and 40% want another...?)

So doing nothing (neither) is sometimes an option but what if there is a threat / a time pressure / external force of some kind and you *need* to make a decision in a few days - how not to leave it too long with 60/40 balance for example?).

My quick thoughts:
Perhaps there isn't a way and that's why capitalism maintains hierarchy to make sure one can overrule another constantly until the top tier hierarchy gets what they want (and overrule it themself if really hierarchy isn't deciding well for them).

For coops / teams perhaps always an internal team has to make / dictate although the whole emotionally deep stuff I feel has to be sorted and can't be ignored constantly without human deprivation.
