This is correct. Consensus opinion might not be the very best of all the possibilities, but is rarely a very bad choice. The other side of this is buy-in. On a great team, it's important to have everyone feel free to put forth an opinion, with backup. And then this process happens. And then it's just as important for everyone to "murder the un-chosen alternative" - in other words, even if a team member very strongly believes their posited solution was correct, and very strongly believes the chosen solution is incorrect - they must murder their solution, and wed the chosen solution. A team, committed as a team, to the team-chosen alternatives over time, is a very powerful team. Likely more powerful than one that only chooses the objectively best solution without full buy-in from the rest of the team. It takes hard and nuanced work from the team leader to cultivate this.
