On the user preferences page on Stack Overflow, there is a "Show experiments" preference toggle.
This toggle allows users to opt out of experiments that offer an opt-out option.
- Enabled: Users will see experiments.
- Disabled: Users will not see experiments that provide an opt-out.
Please note that some experiments do not offer an opt-out option and these experiments will still be shown even if a user has selected to opt-out of experiments.
