SMU Behavioural Sciences Institute director Professor David Chan, who was a panel member on the live results show for Singapore's General Election 2015, commented on the voter's psychology. He suggested that one of the reasons for the large swing of votes towards the PAP was the voters' belief that the Opposition was doing too well. Voters who wanted a PAP government but with more opposition could have gotten the cold feet about voting for the opposition, thinking that others would do likewise too. Professor Chan also noted that the election results may indicate that many voters were convinced by the PAP's policy shifts in response to the angst over the Population White Paper released in January 2013.
