Assumptions-Are they related to cognitive biases ?

Can we say that an assumption is  a cognitive bias.

Assumption-For what there is no evidence but it is still taken to be true.
Google definition-a thing that is accepted as true or as certain to happen, without proof.


cognitive bias is a mistake in reasoning, evaluating, remembering, or other cognitive process, often occurring as a result of holding onto one's preferences and beliefs regardless of contrary information. 
So when a person is making a select assumption could that person be unknowingly tapping into their inherent cognitive bias e.g. assumption from memory=availability  heuristic cognitive bias.

Based on this argument "all research" in which each piece of research has some sort of hidden assumptions has inherent cognitive biases of the researcher.

Fine Graining in the Cancer context

Coarse graining of cellular macrostates can be done at the macroscale. For e.g. if there are cellular macrostates A--->B<=>C---->D, it can be coarse grained to A--->B/C--->D, where A is a group of cancer cells that divide but to a limited extent forming a  pre-cancerous lesion (B) or a benign tumor(C). B and C are interchangeable. When either B or C overcomes the inhibitory signaling of the tumor microenvironment they get converted to a malignant/metastasizing state (D). If  A and D are considered analogous to a  binary switch 0/1 , then the transition between the normal cell and a tumorigenic cell can be considered as :off/on; A/B;0/1 states which can be coarse grained with a single intermediary state B/C.

However each cellular macrostate can consist of  temporally regulated dynamic signal transduction networks. A--->B transition can be considered a series of microstate transitions such as a--->a1--->a2---->a3........b.
Each microstate is a certain conf…
