The psychology of the saver and the psychology of the investor is very closely connected with Keynes' distinction between risk and uncertainty. When the future is uncertain, he thought that a lot of saving would be directed towards securing, securing more, getting more security in the present, rather than building wealth in the future, which was the classical view, you save in order to invest, in order to consume more later on. What he had called the propensity to hoard or liquidity preference would normally be stronger than the inducement to invest.
