One should avoid using analogies while generating alternatives because it leads to manipulation of available data.

Analogies can be a useful tool for generating alternatives by drawing comparisons between different situations or objects. They can help to spark creative thinking and generate new ideas. However, it is important to use analogies carefully and not rely on them too heavily, as they can sometimes lead to flawed or inaccurate conclusions. It is also important to gather and consider all available data when generating alternatives, rather than manipulating the data to fit a preconceived analogy.
