Big Digit Survey

Could you be kind enough to help my friend Ian with a survey which will be useful for his OU course in Astrophysics.

Just three questions which will be collected completely anonymously and for which you will need to measure the middle finger on your dominant hand.

Survey link:

How this relates to Astrophysics is uncertain, it could be one of the Quantum Mechanics things.

Thank you for your time but please do not share this as we want a trusted audience.

This survey does not collect your location, IP address, sign of the zodiac etc.
