defaults

You accept the pre-selected option far too often.

In Germany (opt-in), 12% of the population have registered as donors, while in Austria (opt-out), 99% are classified as potential donors by default.

The difference reflects the legal classification of the population under different default systems rather than active voluntary consent rates.

You are settling for the choices that someone else curated.

Where this comes from

Study: Johnson and Goldstein, 2003, Science
What the check found: While the numbers appear in the referenced paper, they represent legislative default status, not 'consent' in the sense of active personal agreement. Equating these two as equivalent 'consent rates' is misleading.
Confidence: Solid, with limits

One of these every day, and every one names the study it came from. When a finding is contested, it says so.
