Oscillating between denial and recognition of PTSD: Why are lessons learned and forgotten?

Consistent observations suggest that denial of PTSD and blaming of its victims are not isolated omissions or distortions but a pattern that spans over time, crosses national and cultural boundaries, and defies accumulated knowledge.
