There’s a well-known example in philosophy called Buridan’s Ass—a donkey is placed at the exact midpoint between two bales of hay, and being unable to choose between them (because they are identical), it starves to death. Somewhat amusingly, but also unfortunately, digital electronics can run into a similar problem known as metastability; a circuit can get stuck at a voltage roughly at the midpoint between those assigned to logic level 0 and logic level 1.
Oddly, adding a “if it’s hard to decide, choose randomly” circuit doesn’t help; it just creates another ambiguous situation at the borders of the voltage range you designate as “hard to decide”.
