Great apes appear to have “theory of mind”
&gt; After decades of research, it remains controversial whether any nonhuman species possess a theory of mind.<p>It should be important to note that whilst this result isn&#x27;t particularly surprising, there is one giant glaring issue that can undercut this paper.<p>They define theory of mind based on past definitions and research, and base their methodology on methods that have arisen that seem to fit-for-purpose to those definitions.<p>Which would usually be fine.<p>However, during the Replication Crisis, basically everything to do with theory of mind was dashed to pieces. (Worth pointing out that more than 1&#x2F;3 of psychological research was found to be un-replicatable.)<p>One of the main components of &quot;theory of mind&quot;, &quot;embodied cognition&quot; was particularly badly hit by the crisis.<p>So whilst this paper may be unsurprising, it rests on the laurels of stuff that has turned out to be nothing more than a polished turd, making the result questionable until such time as psychology has managed to recover the massive amount of ground lost.
