"You expect input A to produce response B. But in reality, input A and also hidden input C produce response B. You mistakenly attribute the response B to A when in reality, some portion of the response is due to the hidden input or confounding variable C."
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
