Some theorists, like Carlos Santana, have argued that there is a sense in which not all empirical evidence constitutes scientific evidence. One reason for this is that the standards or criteria that scientists apply to evidence exclude certain evidence that is legitimate in other contexts.<sup id="cite_ref-Santana_38-0" class="reference"><a href="#cite_note-Santana-38"><span class="cite-bracket">[</span>38<span class="cite-bracket">]</span></a></sup> For example, <a href="/wiki/Anecdotal_evidence" title="Anecdotal evidence">anecdotal evidence</a> from a friend about how to treat a certain disease constitutes empirical evidence that this treatment works but would not be considered scientific evidence.<sup id="cite_ref-Santana_38-1" class="reference"><a href="#cite_note-Santana-38"><span class="cite-bracket">[</span>38<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-39" class="reference"><a href="#cite_note-39"><span class="cite-bracket">[</span>39<span class="cite-bracket">]</span></a></sup> Others have argued that the traditional empiricist definition of empirical evidence as perceptual evidence is too narrow for much of scientific practice, which uses evidence from various kinds of non-perceptual equipment.<sup id="cite_ref-40" class="reference"><a href="#cite_note-40"><span class="cite-bracket">[</span>40<span class="cite-bracket">]</span></a></sup> </p><p>Central to scientific evidence is that it was arrived at by following <a href="/wiki/Scientific_method" title="Scientific method">scientific method</a> in the context of some <a href="/wiki/Scientific_theory" title="Scientific theory">scientific theory</a>.<sup id="cite_ref-41" class="reference"><a href="#cite_note-41"><span class="cite-bracket">[</span>41<span class="cite-bracket">]</span></a></sup> But people rely on various forms of empirical evidence in their everyday lives that have not been obtained this way and therefore do not qualify as scientific evidence.
