"Zero tolerance" is a popular buzzword among polyticians and other demagogues. Most of the opinion leaders who throw around zero tolerance rhetoric are smart enough to realize that 100% abolition of any phenomenon is generally impossible. More often than not, it's even theoretically impossible!
The PubWan movement isn't about opinions. It is, however, about normative criteria (NormSpec, NormSet). In keeping with its NeutralityPrinciple, pubwan regards the norms (i.e. preferences) of different individuals as equally valid. The movement is also neutral on whether the sources of PubwanParticipant norms are ethical, ideological, æsthetical or for that matter whimsical. The purpose for which pubwan might be created is that of empowering individuals (in general) to impose their own norms on a larger world that for the most part seems not to care. The idea is that individuals deserve more opportunities to live their lives on their terms. Pubwan's purpose is to develop an advanced technology of individual empowerment. Our game plan is to start with informational empowerment.
It is thought by the present author that nonzero tolerance policies can only impede the progress of pubwan objectives. One reason for this is that the methodologies proposed for pubwan so far have been decidedly empirical. Another is that the problem-solving strategy adopted so far starts with both participant-supplied norms and world-supplied constraints. It is also believed that "total victory" may not be a realistic goal when "negotiating" with natural constraints.
The tolerance of nonzero values of parameters is reflected in mathematical techniques adopted by pubwan. One example is the use of piecewise linear functions to describe a parameter called "affordability" in the SampleNormset. Actually, in the sample normset, the term "under-budget" was used. The classical presentation of the "utility function" of microeconomics starts with the assumption that market baskets (subsets of the set of all economic goods) fall into two categories...affordable and not affordable. This is the basis of the concept of "budget line," or "budget hyperplane" The budget hyperplane concept doesn't account for the possibility of borrowing or price haggling. It also doesn't account for the reality of package dealing (i.e. "bundling," see PubwanVirtualObject).
Nonzero tolerance may also be useful in avoiding "divide by zero" errors.
Last time I was at the library (i.e. last time I accessed the internet) I was browsing Wikipedia, where I found a reference to "zero tolerance" in the article on Discordianism, of all things.
Next library trip I shall check this out and see how established theories of zero tolerance relate to my nascent theories of PubWan.
Another trip to the library put a copy of Schumpeter's TenGreatEconomists in my hand. Very interesting...
