Question

Scientists or science writers may extrapolate from a lab study of cells in a Petri dish to the human body. Why is this likely to be "bad science"?

Answer 1

Answer:

It is feasible to extrapolate the outcomes when the cellular mechanisms are the same, but in vivo experimental evidence is required to confirm these results

Explanation:

In molecular biology, it is a routine activity approach to obtain conclusions by using cell lines and then extrapolate outcomes to in vivo studies. However, it is imperative to obtain the confirmation in vivo showed in in vitro conditions (i.e., in vitro results can be used as a working hypothesis). The scientific method is a rigorous process that enables the extrapolation of the results from in vitro experiments when we have the correct model information (although is required to confirm positive findings in the real model).
