Facebook is asking users whether they think it is "good for the world" in a poll sent to an unspecified number of people.
The latest poll appears under the heading "We'd like to do better" when users log in.
Possible responses range from "strongly agree" to "strongly disagree".
Facebook regularly polls users on its service. The latest comes as the company grapples with a privacy scandal and other troubles.
CEO Mark Zuckerberg has said he wants to ensure that Facebook is a force for good in the world.
Whether it is has not been clear amid revelations of it being used to influence elections, spread hatred and steal user information.
In January, Mr Zuckerberg said his personal goal for 2018 is to fix Facebook.
