What feature of Google Forms ensures anonymity in surveys?

The feature that ensures anonymity in surveys when using Google Forms is collecting responses without names. When a form is designed to not collect any identifying information, respondents can provide their feedback or answer questions without fearing that their identity will be linked to their responses. This is especially important in surveys where honest and unrestricted feedback is desired, as participants may feel more comfortable sharing their thoughts if they know their identities remain confidential.

In contrast, setting forms to public by default, sending surveys via text messages, or automatically recording email addresses do not support anonymity and can instead compromise the privacy of the respondents. Public forms may be accessible to anyone, text messaging does not inherently make responses anonymous, and recording email addresses directly identifies respondents. Therefore, ensuring that responses are collected without names is crucial for maintaining anonymity in surveys.
