A common dark pattern in UX is the "pre-checked box" or deliberately confusing button copy that nudges you to buy extras or opt into recurring charges. These are design choices that benefit conversion rates but not consumer clarity. A classic example: during checkout you see an add-on pre-checked; if you don't notice, you've opted in. Regulators and consumer-rights advocates call these "manipulative defaults." The practical workaround is careful scanning, using browser autofill cautiously, and switching off pre-checked options. This question checks whether you can identify a clear example of a dark pattern.
