“To visualise this model, Longo and Haggard asked volunteers to hide their hand under a board and use a baton to indicate the position of ten landmarks – the tip and base knuckle of each finger. Their answers were surprisingly inaccurate. They underestimated the lengths of their fingers by anywhere from around 5% for their thumb and over 35% for their ring and little fingers.” Wow, stick your hand under your desk, use a Post-it to mark where you think your fingers should be. 5% underestimate is about right.
