Have you ever done this while taking a multiple choice test?

  • My personal favourite is the Tiger Special. Four answers: One correct, one a joke, and two specifically to highlight people who pretend to know what they are talking about. For instance:

    The Haar measure is a non-zero measure, μ, on a sigma-ring S generated by compact subsets of a topological group that is logically compact, such that the measure is left-invariant (μ(χA)=μ(A) for all χ in G and A in S) or right-invariant (μ(Aχ)=μ(A) for all χ in G and A in S). In the commutative case these coincide, and on a compact group any left-invariant measure is also right-invariant, and vice-versa. Such a measure is unique up to a multiplicative constant. Name an example of this.

    a, Lesbegue measure
    b, Kronecker's lemma
    c, Fenchel conjugate
    d, Dogface

    If people answer a or d, they're worth knowing because they're either clever or flippant. If they answer b or c, avoid them like the plague because they don't have the first clue about anything but will happily pretend that they do.
