My sentence is:
Hence this option is free of abundance bias
Say, if a doctor sees 100 patients with X and someone who has Y (which has symptoms similar to X) comes in. The doctor fails to consider any subtleties that might make it different from X and just diagnoses X. This doctor has "abundance bias" because the X was more common. You could say it's actually confirmation bias but that'll be when the doctor diagnoses based on his subjective experience rather than X being more widespread.
I want to replace the term "abundance bias" with the properly defined term rooted in psychology/cognitive sciences that denotes that the option will account for all subtleties and won't be biased towards stuff that happens to be more common.
