Full origin of opt out →Frequently Asked Questions
What is the difference between opt out and opt in?
Opt in means nothing happens unless you actively say yes; opt out means it happens automatically unless you actively say no. Opt-out schemes produce far higher participation, which is why they are used for pensions and organ donation and why data-protection law restricts them for marketing.
Is it opt out or opt-out?
Use two words for the verb, as in 'you can opt out today', and a hyphen for the noun and the adjective, as in 'an opt-out clause' or 'an opt-out system'.
Can you opt out of automatic pension enrolment?
In schemes with automatic enrolment you normally can, within a set window after being enrolled, by telling the scheme provider rather than your employer. Opting out means giving up the employer's contribution as well as your own, so it is rarely to your financial advantage.
