  • Illusion of invulnerability
  • Everything is going to work out all right
    because we are a special group. - 95 to 97
    percent assurance of success
  • They placed an exact estimate of assured success
    without thinking of their alternate outcomes
  • Inherent mortality of the group
  • Were saving POWs how can it be bad
  • How could anyone not approve this? (President

Son Tay Raid
  • Collective rationalization
  • General Blackburn, General Bennett and Admiral
    Moore meet to decide if it is a go
  • Blackburn was the sponsor and felt the mission
    was the only option, but had fears that Bennett
    or Moore would feel different
  • Despite recent intelligence they felt the same.

Son Tay Raid
  • Out-group stereotyping
  • Planners lamented the lack of HUMINT and over
    reliance on technical means
  • Yet they discarded all HUMINT that did not
    support a GO decision

  • Admiral Train admitted 12 hours before the raid
    they had almost indisputable evidence the campe
    was empty
  • A Four Star Flag Officer remained silent to be a
    team player

Son Tay Raid
  • Illusion of unanimity
  • By remain silent the group interpreted it as
  • If the fall out was bigger, like Watergate, there
    would have been more dissenters afterward
  • Direct pressure on dissenters
  • After being told the camp was empty by DIA
    Intelligence agents General Blackburn scolded
    them How the hell can you make heads or tails
    out of the data
  • Shortly after they thought that the prisoners
    were moved back
