Opinion Sort

«Bullshit is unavoidable whenever circumstances require someone to talk without knowing what he is talking about. Thus the production of bullshit is stimulated whenever a person’s obligations or opportunities to speak about some topic are more excessive than his knowledge of the facts that are relevant to that topic.

This discrepancy is common in public life, where people are frequently impelled— whether by their own propensities or by the demands of others—to speak extensively about matters of which they are to some degree ignorant.

Closely related instances arise from the widespread conviction that it is the responsibility of a citizen in a democracy to have opinions about everything, or at least everything that pertains to the conduct of his country’s affairs.

The lack of any significant connection between a person’s opinions and his apprehension of reality will be even more severe, needless to say, for someone who believes it his responsibility, as a conscientious moral agent, to evaluate events and conditions in all parts of the world.»

(From Harry G. Frankfurt's On Bullshit)

Opinion Sort

In a world where it is more important to have a quick opinion than a thorough understanding, I propose this novel sorting algoritihm.

def opinion_sort(list: List[Any], post: Callable[List]):
    list: a list of elements to sort in place
    post: a callable that requires a sorted list as input and does
          proper error checking, as they should do
    if list[0] > list[1]:
        swap(list[0], list[1])
    while True:
            # Assert opinion: "It is a sorted list!"
        except NotSortedException as e:
            # Someone disagrees, and they have a good point
            swap(list[e.unsorted_idx_1], list[e.unsorted_idx_2])
    # The list is now sorted, and the callable has to agree

This algorithm is the most efficient sorting algorithm, because it can sort a list by only looking at the first two elements.
