Summary

• Algorithms aren’t neutral; they’re built with intent.

• Designs that chase engagement boost some voices and drown out others.

• The ethical question: should platforms put profit above the public good?

• How we respond together will help determine whether digital spaces stay tools for empowerment or become traps of manipulation.

  
  

Every swipe, every scroll, every minute in front of a glowing screen is part of an experiment we never agreed to join. Social media and digital platforms promise connection, entertainment, and information. But beneath their polished interfaces is an algorithmic design that feeds on compulsion, not our well-being.

These algorithms aren’t just passive code. They’re carefully engineered around the psychology of reward, habit, and emotion. Their aim is straightforward: maximize engagement. The effects on mental health, society, and even democracy, however, are anything but simple.

Algorithms Know More Than We Admit

Recommendation systems are often framed as helpful tools that “show us” what we like. The reality is more unsettling. Algorithms don’t just reflect our interests. They shape them. By constantly serving up what we already interact with, platforms create feedback loops that narrow our worldviews and deepen our dependence.

When you linger on a post, out of joy, outrage, or curiosity, the system records that microsecond of attention. It weights that pause and folds it back into its model of you. Over time, your feed stops being a mirror and starts steering your clicks before you even decide.
