Personally - trust the gut after plenty of experience.....then try and quantify that.
Would it be possible to elaborate on this? Could you share an example - does not have to be trading related.

You may be setting up a straw man by implying that 'analytical problem solving' does not belong in the realm of discretionary trading. It most certainly does.
Intuition often carries a negative connotation. But it is simply a mechanism. The problem solving in this case then becomes a matter of first identifying the right heuristics and then practicing how to apply them in real time.
Intuition without such research and practice can lead to disaster as the mechanism is simply executing fear/greed biases. But once the right heuristics are in place, there are few things as powerful as discretionary decision making based on a platform of systematic analyses.

There is always the trap of afterwards finding excuses to justify your decision, but that is usually when you have done something....whereas I prefer to trust my gut as to when to avoid something.
This made me think - Is trusting your gut similar to following rules of thumb whereby its impossible to quantify because they are heuristics and are not meant to be complex and quantifiable but a quick and dirty solution.....(in answering myself not really) or is it simply that instinct by its very nature is not meant to be quantified. Its simply that indescribable feeling that puts a lot of complex things together in an emotion quickly.

Just read this thread:

I am fascinated by traders with a STEM background (a college degree in science, technology, engineering or mathematics) who decide to go the discretionary route rather than the systematic route.
What is it about the "gut-feel" approach to trading that is more appealing than the analytical problem-solving approach they learned in college?
That link you provided is basically an ad for PAL, not an objective evaluation of backtesting. "Any strategy testing you do without PAL is crap.". Yeah, right.Science is only good if it is properly understood. More traders are now realizing the limitations of backtesting and they are worse than any discretionary bias. Here is an interesting angle:
" Traders who use such products without understanding these realities of repeated backtesting with many degrees of freedom become the victims of their own ignorance and have no chances of ever finding a true edge unless they get to the bottom of this but that requires another edge in the form of an understanding of what must be done to avoid the pitfalls of such processes."

It boils down to the fact that what is at the heart of automated trading, the backtesting routine, is a problematic process as it turns out. This is the reason for a current massive switch to gut trading. If you fail, at least it was your mistake and not some data mining bias thing.
