Although I don't necessary agree with your choice of the term, I find
it interesting that you should use the biological term "disease";
according to a post  entitled "Re: Re: Smalltalk Data Structures
and Algorithms," by K. K. Subramaniam, dated "Mon, 29 Jun 2009

It's an interesting coincidence that you should hit upon the term
"disease," which also derives from biology.
It's not just "the sheer unpredictability of it all" that is "the
reason for the anthropomorphics"; it is the fundamental difference of
the basis in biology vs. computational mathematics. Haskell (and FP)
derive from the latter; Smalltalk (and OOP) derive from the former.
Biological structures also contain "all kinds of hidden state and
dependencies"; in that sense, objects are similar to biological
structures, and are more easily anthromorphized on that account.
Functional programming functions, on the other hand, are not similar
to biological structures, and hence are not easily anthromorphized;
instead, they are similar to mathematical functions.
I wouldn't necessarily say that "anthromorphics ... [is] a symptom of
a disease," though. Anthromorphics simply uses terms from biology,
from which concepts in Squeak (and the OO paradigm thereof) derive.
