At first glance, this sign-up screen may look straightforward, but it uses a subtle dark pattern known as "pre-selection" to automatically opt users in to receive marketing emails.

The "I would like to receive updates through the newsletter" checkbox is pre-selected by default. This means that users automatically agree to receive marketing emails unless they notice the checkbox and actively uncheck it. While this may seem like a minor inconvenience, it has significant implications for user consent.

Why is this a problem?

  • Assumed consent: Instead of requiring users to actively opt-in, this design assumes consent by default. Many users may complete the form without realising they've agreed to receive newsletters.
  • Take advantage of user inertia: Most people don't check every box on a form. Pre-selecting this option takes advantage of the likelihood that users will simply accept the default setting.
  • Regulatory concerns: Depending on the region, this practice may violate privacy laws such as GDPR or CCPA, which emphasize clear and affirmative user consent for marketing communications.

How to create a more user-friendly and transparent registration process:

  • Default to unselected: Let users actively choose to opt in, ensuring that their decision is intentional.
  • Use clear language: Provide straightforward and non-deceptive explanations of what users are agreeing to.
  • Respect privacy by design: Make it as easy to opt out of marketing emails as it is to opt in.
