Six years after COVID-19 disrupted childhood around the world, new research following the same children from before the pandemic through today finds that the damage was far less widespread than early warnings predicted. A Special Section in the Society for Research in Child Development's flagship journal Child Development, synthesizing 17 long-term studies across six countries, finds that most children's health, learning, social development, and wellbeing recovered substantially. Setbacks that persisted were concentrated among children who already faced other risks before the pandemic began. This new research, tracking children over a longer period, tells a different story: pandemic impacts were real and wide-ranging, but not as severe as initially feared, and many effects weakened over time. The children who fared worst and recovered more slowly were disproportionately those shaped by pre-existing risks — not the pandemic alone.

With engagement being their main goal, their recommendation algorithms typically identify which content a user engaged with most in the recent past and efficiently suggest more of the same.

But as marketing professor Samsun Knight points out in new research, familiarity isn't the same as taste, which can take longer to develop.
