I understand that part of the issue with CB is that they are so ingrained and hard to work around, but I see them as being pretty confounding to trading success, so wondering how people have found ways to get around them having too big an influence on trading. A few examples...
Anchoring bias - tendency to anchor onto the first bit of information you receive.
Recency bias - tendency to overvalue the most recent piece of information because that info is fresh and salient
Loss aversion bias - tendency to dislike losing a lot more than enjoying winning, can lead to inaction.
Bandwagon bias - tendency to want to be a part of the crowd, to do things because others are doing them or believing them
Confirmation bias - tendency to stick with information that confirms out point of view and dismissing info that goes against it
Overcoming cognitive biases
I think some of it comes down to changing as a person, that's my experience anyhow.
I'm a different person from the one I knew before learning to trade. I can spot somebody that is going to struggle to trade from the way they project themselves. You often need to think and act in a way that just isn't 'normal' as the cognitive biases are there for social reasons and difficult to overcome.

Bandwagon bias is understandable if you're at a party and you're the only one who's not interested in football, but when it comes to trading you have to understand from the outset, that if you do what everybody else does, either you don't win or everybody wins, which isn't possible.arbitrage16 wrote: ↑Mon Feb 19, 2018 9:07 pmI understand that part of the issue with CB is that they are so ingrained and hard to work around, but I see them as being pretty confounding to trading success, so wondering how people have found ways to get around them having too big an influence on trading.

Loss aversion bias is another trading no-no that leads to disaster.
The other biases you mention are probably harder to eliminate but I think are less critical to trading, or at least won't lead to disaster.
I remember an experiment where a group of people were shown a video of a job interview. The 50% that saw the interviewee slip-up at the beginning but sound more confident at the end, were more positive about his presentation the the other half who saw the edited version where he was confident at the beginning but slipped up at the end, suggesting most people have recency bias.
Personally though, I think it is easier to eliminate such biases when focusing on something specific such as trading, as it is to do in day-to-day life when you're out socialising.

That's a useful pointer, thanks. I am big on personal development and an avid reader, so if there are any books or articles, or even exercises you'd recommend on overcoming this, I'd appreciate it.Euler wrote: ↑Mon Feb 19, 2018 10:17 pmI think some of it comes down to changing as a person, that's my experience anyhow.

Thus far the most useful I have found have been Thinking Fast and Slow and The Chimp Paradox.

Show a little respect. Euler has given more useful advice here than anybody else.
Oh now I see... you think he was reading on a fast and a slow pace

He meant this, and maybe you should read the articles of Brett Steenbarger..

A little shame the small print doesn't quite come through, although I believe each can be pumped straight into google & has a lot of material on each bias.

I was considering a visit to Hook sometime but now I'm terrified that I'll get a thumbs down from the Emperor the moment I step inside the arena.
Seriously though a remark like that is how 3 pint lunches begin, you can't just stop there!

What do you mean? What kind of behaviour would lead you to believe someone will struggle?
Do you mean that you'd expect people who are lower on social skills (and I find such people are often high in terms of their analytical skills) would usually make better traders?You often need to think and act in a way that just isn't 'normal' as the cognitive biases are there for social reasons and difficult to overcome.
