As William of Ockham very rightly observed in what came to be known as Occams Razor, "All other things being equal, the simplest solution is the best."
And all other things are very equal in trading, but by absolutely no means only there.
Most things in life are really simple enough - if not maybe easy always -, once you succeed in seperating the
noise from the few, truly
success relevant factors.
It's almost always lack of understanding or a need to stoke a bruised ego that leads to undue complexity.
Ego driven efforts at problem solving only make you want to be
right over wanting to be
successful.
As amazing as it is, but a clear majority of people prefer being right over having success.
A very bad sign is when people aren't able to explain in a few words what constitutes the relevant essence of what they are on about, what the
20% of their effort that generates 80% of their results is.
Jack Welch) said it and did it,
Business is simple, undue complexity is almost always nothing than an attempt to camouflage lack of true understanding.
Harvards department of psychology did a famous complexity experiment where two groups of students had to come up with explanations to simple problems. The first group got the correct evaluation from the professors, ie if they had come up with the correct explanation they received a "correct", if not they got a "wrong", while the second group got
random evaluations, so that even if they were right they might have received a "wrong" and vice versa.
The first groups solutions were all admirably simple, while the second groups explanations became increasingly complex as they tried desperately to force the inexplicable facts to fit their ever wilder theories.

It
Simple,
Stupid !
