@business· How VCs Think

Tubulin gene variants can bias left-right hand preference because altered microtubule behavior can make signaling molecules accumulate unevenly in neural progenitors, nudging spinal and brain circuits to develop more strongly on one side.

AI models can act like Clever Hans because they latch onto incidental input patterns that correlate with labels, producing correct outputs by exploiting those shortcuts instead of learning the intended task.
