Justin Rosenstein: No Dislike Button on Facebook

In this interview excerpt, Justin Rosenstein recounts his progression at Facebook from product management to engineering leadership, highlighting his work on Facebook Pages that enabled non-human entities to join the social graph. He describes how a hackathon project sparked the development of the Like button, driven by the observation that users sought low‑effort ways to express affirmation. Rosenstein explains the design goal of making positive interaction as simple as a single click, and argues that the absence of a Dislike button reflects a deliberate, opinionated choice to shape the social graph toward mutual support rather than negativity. He notes that despite frequent requests for a Dislike button, the platform’s infrastructure is intended to encourage affirmation and help users help each other.
