Science is a rather vague term. What you mean is the scientific culture popular in usa, europe etc. Which has definite biases in its vindication process.
But TCM would have none of these, so no, it's not "due to bias".
It's a means of predicting the success of a hypothesis. It is not a collection of beliefs.
There are plenty of successful hypotheses that science has "proven", which are now accepted by the "scientific community", but the word has an actual definition.
