How a crossword could become a test of morphic resonance
Morphic resonance is the idea that once a pattern has been learned, it becomes easier for similar systems elsewhere to learn it too. Its proponents describe this influence as a kind of nonlocal field: a connection not carried by an ordinary signal such as sound, light, or a message. The crossword example applies that claim to human learning. If one person solves a puzzle, perhaps another person, without hearing about it, might find a similar puzzle easier.
The proposal is not simply that people copy answers. It imagines that prior acts of learning leave behind a pattern that later learners can somehow draw on. The rat-maze example makes the same claim in a more measurable setting: if rats in one place master a maze, rats elsewhere might learn that maze faster.
Why the idea is difficult to distinguish from ordinary learning
A person’s crossword performance can change for many familiar reasons: experience with puzzles, knowledge of the clues’ subject matter, or whether the answers have appeared in other puzzles. To make a case for resonance, those influences would need to be separated from the proposed effect. The comparison would also have to be arranged so that the later solver could not learn about the earlier solution through ordinary channels.
That is why a striking coincidence—two people solving the same clue, for instance—would not by itself demonstrate a hidden connection. The claim concerns a measurable change in learning, not merely the fact that people sometimes arrive at the same answer.
The hope, and the leap
For proponents, the appealing possibility is that learning could benefit others even when no teacher, book, or communication carries the knowledge between them. But extending a proposed effect in animals to human puzzle-solving is an additional step, not a consequence established by the example itself. The crossword remains an illustration of what believers hope morphic resonance might do: let one person’s solved puzzle make a distant person’s next one just a little easier.
