Privacy information for the EA survey

We take your privacy extremely seriously, are experienced in normal privacy practices, and as you can see below go above and beyond these in many respects.

Data security

Your responses will be saved within robust software the security of which has been widely tested, administered by an experienced sysadmin. Only anonymised datasets (ie. ones not containing any names or email addresses) will be shared with people besides those specified below.

You can revoke permission to share details

At various points in the survey you can explicitly opt to share certain details. You can revoke this permission at any point by logging into your EA Profile account and editing your details (which is the preferred method) or as a fallback by emailing

Name and email address

Giving your name and email address is optional (though recommended and helpful - several people have expressed the wish that they'd done so when later requesting to make some of their answers public). If you do provide them, they will only ever be visible to a carefully chosen subset of the .impact survey team, and also specific people within the Centre for Effective Altruism and 80,000 Hours. CEA and 80,000 Hours will not email you. .impact will only use your address to send followup messages about the survey (the ability to do this would be very helpful), and you will be able to unsubscribe from these; however in previous years the only messages sent have been one asking people in certain locations about doing local EA outreach, and one giving login details to those who chose to create EA Profiles.

Any data that is shared beyond this will have names and email addresses removed. Your name and email address will be saved only within robust software the security of which has been widely tested. In the past, only computer scripts have "looked" at the vast majority of these names, and when comparing cross-year data we replace names with numeric IDs that pick out responses by the same individual across diffeent years.

Personally identifying information you include in other answers

Volunteers check answers to remove these, though cannot guarantee total coverage.


If you used an identifying token to access this survey, please rest assured that this token will not be stored together with your responses. It is managed in a separate database and will only be updated to indicate whether you did (or did not) complete this survey. There is no way of matching identification tokens with survey responses.
