Fluid and Crystallized Intelligence

There are arguably two types of intelligence. Fluid intelligence is your ability to reason quickly. It relies on the ability to hold attention and benefits from a strong working memory. Crystallized intelligence is your ability to apply knowledge from prior learning that was stored in your long term memory. To illustrate how the two work together, we created a short fairytale - a story of a young man, who wants to save a princess that was captured by an evil witch.
