Answer: an Olympic swimming pool measures 50 m (length / span), which is 1.3× as big as the reference, a Space Shuttle orbiter at 37.3 m.
An Olympic pool is exactly 50 metres long.
How people guessed: across 13 runs the typical guess was 50.9 m — almost exactly right.
Answer: Australia measures 4,000 km (length / span), which is about 1.1× smaller than the reference, Brazil at 4,320 km.
Australia is nearly as wide as the contiguous United States, with a tenth of the population.
How people guessed: across 13 runs the typical guess was 5,340.4 km — 34% too large. The most common miss is picturing Australia far bigger than Brazil really allows.
Answer: the Apollo Lunar Module measures 6.9 m (height), which is 1.3× as big as the reference, an adult giraffe at 5.2 m.
It stood about as tall as a two-storey house, and only the top half ever came back.
How people guessed: across 13 runs the typical guess was 6 m — 13% too small.
Answer: a leafcutter ant measures 1.3 cm (length / span), which is about 1.2× smaller than the reference, a mosquito at 1.5 cm.
Leafcutters routinely carry many times their own body weight.
How people guessed: across 13 runs the typical guess was 2 cm — 52% too large. The most common miss is picturing a leafcutter ant far bigger than a mosquito really allows.
Answer: a VR headset measures 20 cm (length / span), which is about 1.4× smaller than the reference, an American football at 28 cm.
Most of the bulk is the gap the lenses need in front of your eyes.
How people guessed: across 13 runs the typical guess was 31.3 cm — 56% too large. The most common miss is picturing a VR headset far bigger than an American football really allows.
