In my experience, people who talk about objectivity aren't worth ascosiating with. They are poor at being emotionally open or supportive and use "objectivity" as an excuse or crutch for their shortcomings.
For me, I acknowledge, I have certain biases and charitability to things I can't help. It is more difficult to judge things objectivly when you are involved. But... How often do you really even need to be judging? Judging, arguing and criticising are poor ways to live.
I would rather be playful with friends than confrontive.
If you want an actual answer to "Ultimate truth". Try reading Viktor Frankls "mans search for meaning". I think something close would be affecting ones own choices personally. The most exhausting thing to do.
