The click of a stuck problem
A rope folded in half, one cut: the answer arrives all at once, after your first picture of the problem breaks.
Your first mental picture of a puzzle usually carries a hidden wrong assumption.
Being stuck is the assumption fighting back, not a lack of intelligence.
Re-picturing the problem, drawing it, folding it in the mind, is what releases the click.
Then and now
Duncker's stuck-then-click observations now have EEG and fMRI signatures: the aha moment is real, measurable brain activity.

Classic studies of how first framings (like functional fixedness) block solutions until the problem is re-represented.

The aha moment has a measurable neural signature: insight is a distinct mode of problem-solving, not a lucky guess.
What we do and do not claim
Insight puzzles teach re-framing. A miss means the frame held, and the reveal hands you the better frame.
