AI or Human?

In this experiment, you will be presented with a series of short social-media texts. Each text was written either by a person or generated by AI. We ask you to read each text carefully and share whether you believe it was written by a Human or by an AI. An "explanation hint" will be shown alongside each text to help you decide.
