A surprising new discovery suggests that fear may cause the brain to blur the line between danger and safety rather than distinguish them more clearly. By observing brain activity in mice using augmented reality, scientists found that memories of threatening and harmless environments began to overlap, potentially allowing faster responses to danger. This "better safe than sorry" survival mechanism could help explain why people with anxiety or PTSD sometimes experience intense fear in completely safe situations.
