Details are provided in Chapter 1 of the 2107 book ‘The Leadership Hubris Epidemic’ [£87.50, Palgrave Books] in which professor Peter Garrard (at St. George’s, University of London) writes that the effects of Frontotemporal Dementia (FTD) can be compared with those suffering from Hubris Syndrome (HS) – and who exhibit (amongst other things) :
“Excessive confidence in their own judgment and contempt for the advice or criticism of others” and
“[…] loss of contact with reality; often associated with progressive isolation.”
For: a recent example of the multi-billion dollar grief which ‘The Leadership Hubris Epidemic’ can inflict, see: ‘Recklessness, hubris and greed’ – Carillion slammed by MPs (The Guardian, 16 May 2018)
Also: don’t miss The Daedalus Trust which has been drawing attention such things since 2011.
