Editing Extrapolation (section)

==Extrapolation arguments==
Extrapolation arguments are informal and unquantified arguments which assert that something is probably true beyond the range of values for which it is known to be true. For example, we believe in the reality of what we see through magnifying glasses because it agrees with what we see with the naked eye but extends beyond it; we believe in what we see through light microscopes because it agrees with what we see through magnifying glasses but extends beyond it; and similarly for electron microscopes. Such arguments are widely used in biology in extrapolating from animal studies to humans and from pilot studies to a broader population.<ref>{{cite book |last=Steel |first=Daniel |date=2007 |title=Across the Boundaries: Extrapolation in Biology and Social Science |url=https://oxford.universitypressscholarship.com/view/10.1093/acprof:oso/9780195331448.001.0001/acprof-9780195331448 |location=Oxford |publisher=Oxford University Press |page= |isbn=9780195331448}}</ref>

Like [[slippery slope]] arguments, extrapolation arguments may be strong or weak depending on such factors as how far the extrapolation goes beyond the known range.<ref>{{cite journal |last1=Franklin |first1=James |authorlink=James Franklin (philosopher) |date=2013 |title=Arguments whose strength depends on continuous variation |url=http://ojs.uwindsor.ca/ojs/leddy/index.php/informal_logic/article/view/3610/3000 |journal= Informal Logic|volume=33 |issue=1 |pages=33–56 |doi=10.22329/il.v33i1.3610 |access-date=29 June 2021}}</ref>
