About Hindsight
History quizzes whose every answer was written twice, independently, and cross-checked before a single question was generated.
Where the answers come from
Two sources, both dual-authored. A catalog of 149 historical facts – the years of the wars,
the people of the revolutions, the gods and their domains – was filled in twice by independent
authors against the same fixed questions, and the two copies compared value by value: all 149
agreed after seven surface-form differences were reconciled. The list of all 47 US presidencies
– names, parties, years – agreed on every field at the first comparison. Where authors cannot
both vouch for an answer, the site asks no question.
What the questions deliberately avoid
Settled history only. Nothing here depends on this year’s news, a contested interpretation,
or a date scholars still argue about. Where a fact is legend rather than record – the founding
of Rome, the deeds of the Olympians – the question says so.
What playing costs you
Nothing: no account, no download, no tracking of your answers. Your best score per quiz is
stored in your own browser and nowhere else.
