consider a function y = f(x)
y is known if and only if x is known
y = 0 or 1 for all x
y = psychological state
x = thought
Here's the literal explanation:
Human psychological state is a function depends on thought. (There may be other dependency. for example y = g(w) where w is the degree of adrenaline.) Once a thought exists within a human's mind, the psychological state is also defined. Suppose psychological state can be classified into good or bad depends on that person, and that the value of thought is roughly proportional to the amount of knowledge obtained, than we can obtain a graph observing the effect of thought on the human psychological state of a person throughout his/her life. What is observed is a very likely a random function, where the psychological state fluctuates with the increase in knowledge. The result is almost the same if y is the degree of happiness and x is the degree of thought, where happiness fluctuates with the increase in degree of thought.
Thought have power on altering the psychological state but no direct effect on improving it. A childish boy may be happier than a sophisticated man and vice versa. Interesting observation is actually that psychological state tends to be more "stable" with the increase in age but not the knowledge and people becomes more reluctant to the change in their living environment. This may due to the incapability of changing mental model. But it's still hard to say until enough research is conducted. What I want to point out is that「人は真実を知れば幸せになれると思いがちである。────しかし大抵の場合、逆の結果しか産み出さない。」may not true.
Humans used to choose and stay at a suitable state/stage of thought to maintain their preferred psychological state (x retained or developed in a normal pace). If the preferred psychological state collapses (y changes from good to bad), they just try to think more and hope to reach another preferred psychological state and stay there (x varies in order to recover y back to good).
