Quote from outsource:
An exact science is any field of science capable of accurate quantitative expression or precise predictions and rigorous methods of testing hypotheses, especially reproducible experiments involving quantifiable predictions and measurements. Mathematics, physics, chemistry, as well as parts of biology, psychology, and the social sciences and TRADING can be considered as exact sciences in this sense.
sounds like a quotation to me , isn't it?? or these are your own words? "Evidence based technical analysis" - I'd bet this is where it comes from but maybe I'm mistaken

very good book by the way, will deprive you of illusions..chapters on psychology should be dealt with in 'Psychology' section on this site instead of ' how to change your subconscious mind' , 'getting rid of your ego' and the like..haven't finished reading yet

one good quote from the book on correlations:
'First, let's consider what happens when people are shown data for
two variables) 10 that are in fact related but which are not expected to be
correlated. Experiments have shown that they are unable to detect the
relationships unless the correlation exceeds approximately 0.70, on a
scale of 0 to 1.0, where 1.0 represents a perfect correlation and zero rep-
resents no correlation. A correlation of 0.70 is far stronger than anything
likely to be encountered within the domain of TA. ))) This finding suggests
that subjective TA analysts relying on informal/intuitive data analysis
methods will be prone to missing valid correlations that they do not ex-
pect to exist.
What is even more relevant to the problem of illusory TA knowledge
is the tendency to perceive correlations that do not exist."
