Choh Boh Lim was wrong. Here is a simple explanation for massive groupthink in PAP

[Confuseous]

In the past few elections, a growing number of ministers are recruited from the SAF and civil service - typically from highest echelons. It is hard for career officers who benefited greatly from the PAP system to say no when asked to join the PAP even though they probably prefer to be parachuted into jobs in GLCs such as Singapore Technologies, SingTel etc where they can escape public scrutiny and criticism. In the long run this is a unhealthy trend for Singapore - it undermines the ability of the govt to transform and changeas they recruit senior people from their monolithic power structure into govt.
