In groups of people (committees) there tends to be an inclination, for the sake of consensus, to demand compromise from all the participants rather than evaluating (debating) whether certain points of view are wrong and should be changed and whether they are right and to remain unchanged. This is why Kierkegaard makes the claim “the crowd is untruth“; the introduction of a single untruth will corrupt the truth and, therefore, make the consensus untruth. Here’s Kierkegaard on the subject:
There is a view of life which holds that where the crowd is, the truth is also, that it is a need in truth itself, that it must have the crowd on its side. There is another view of life; which holds that wherever the crowd is, there is untruth, so that, for a moment to carry the matter out to its farthest conclusion, even if every individual possessed the truth in private, yet if they came together into a crowd (so that ‘the crowd’ received any decisive, voting, noisy, audible importance), untruth would at once be let in.
For ‘the crowd’ is untruth. Eternally, godly, christianly what Paul says is valid: “only one receives the prize,” [I Cor. 9:24]
— Søren Kierkegaard. The Crowd is Untruth
Here’s the whole scripture to which he referred:
24 Do you not know that in a race all the runners run, but only one gets the prize? Run in such a way as to get the prize.
— Apostle Paul, 1 Corinthians 9:24 (NIV1984)
