The claim that violent video games have no negative behavioral effects is refuted by substantial empirical evidence, including meta-analyses, longitudinal research, and experimental studies demonstrating links between violent game exposure and increased aggression or desensitization.
The claim asserts that violent video games have absolutely no negative behavioral effects. Multiple high-quality retrieved papers (such as Anderson et al., 2001; Möller & Krahé, 2008; Giumetti & Markey, 2014) directly refute this by showing empirical evidence that violent video games increase aggressive behavior, hostile attribution bias, and aggression-related thoughts. Therefore, the balance of evidence clearly contradicts the claim.
