The difference between real-time action and slow motion is central to the debate. A report citing research from KU Leuven says leading referees gave consistently harsher decisions when they watched the same fouls in slow motion rather than at normal speed.
That matters because football is played at speed. A challenge that appears reckless when isolated may look less severe when judged alongside the players’ movement, balance and reaction. Replay can clarify what happened without fully explaining how much blame should follow.
The problem is not that technology is inaccurate. It is that accurate images can create a false sense of certainty around decisions that remain subjective.
Referees retain the final authority at a pitch-side screen, but the presentation of evidence carries influence. Once a selected angle highlights a point of contact, the official may be drawn toward the interpretation built into the replay.
That can produce a form of anchoring. The original live assessment becomes something to defend or overturn, rather than the starting point for a balanced review. More footage does not automatically mean better judgement if the most dramatic frame dominates the process.
Football should consider requiring officials to record an initial view before consulting replay technology. The referee could state whether the incident was a foul, whether it met the threshold for a card and what factors shaped that judgement.
Replay would then test the decision rather than create it. This would not eliminate mistakes, but it could protect officials from being overpowered by slow motion and give reviews a clearer structure.
The next major tournament will offer another test of football’s technological direction. VAR should remain a safety net, but the referee’s first reading of the game must not disappear beneath the replay.
