Afterwards, researchers tested each participant's understanding by asking them to predict which of two wheels would cover the distance faster.

The study found: "The average wheel speed increased across generations while participants' understanding did not."

A further 14 chains of students completed the same process, but this time they could write down a theory to pass to the next participant.

Wheel speed rose at a similar rate as that seen in groups who passed on no written instructions, but once again understanding "barely changed across generations."

The researchers said: "Most participants actually produced incorrect or incomplete theories despite the relative simplicity of the physical
