It's been shown with science (Google antonio r. damasio emotion decision making). So I guess that means it's objective? People who are injured in the part of the brain that generates emotion have trouble making decisions.
Using logic and refining or rationalizing is another layer.
This is why I've gotten annoyed with some logical types. When they think they're skipping that part. It's like convincing yourself u don't poop.
If you're good at making intelligent decisions or justifying them logically it's still a fantastic skill to have and you should be happy about it, even if they were formed by emotion at first. I won't tell anyone else.
