A Conundrum(?) about Empirical Knowledge and Empirical Belief.

addenda 031819
In so far as a scientific statement speaks about reality, it must be falsifiable; and in so far as it is not falsifiable, it does not speak about reality.” -- Karl Popper

No amount of experimentation can ever prove me right; a single experiment can prove me wrong. -- Albert Einstein
BEGINNING:The Empirical Conundrum.
Original Assumption: Knowledge and Belief are not the same.
Belief may be a component of Knowledge, but Knowledge need not be a component of belief. Some beliefs are not knowledge.
Proposition A: Empirical Knowledge Claims are Defeasible (falsifiable), by virtue of their being empirical.
, i.e. defeasible means subject to withdrawal by virtue of possible (though maybe as yet unknown) countering evidence, CE. (See Three Human Dimensions of Conceptualization.)

Then,
Proposition B: Empirical Knowledge claims are, at best, Empirical beliefs.
So, it follows that
Proposition C: if something is at best an Empirical Belief. it is not Empirical Knowledge,
according to the Original Assumption.

Proposition C applies to anything that is claimed to be empirical evidence.

Thus Empirical Knowledge is not defeasible and consequently not empirical, gotten via the contrapositive of Proposition A.

Attempted Rebuttal.

But what is this CE? Is it Empirical Knowledge? If so, then by Proposition A, it is defeasible, ergo, merely Belief.

Thus, if counter-evidence CE is merely Empirical Belief; it is not really counter-evidence. Thus, Propositions B and C are gainsaid and consequently, Empirical Knowledge is, indeed, defeasible. (GO BACK TO BEGINNING.)

When you've gotten tired going repeatedly back to the Beginning, in considering the vulnerabilities of the above argument, see both

Searching for “Reality"? Stipulate A Turtle!

edited 102119
"What you have told us is rubbish. The world is really a flat plate supported on the back of a giant tortoise." The scientist gave a superior smile before replying, "What is the tortoise standing on?" "You're very clever, young man, very clever," said the old lady. "But it's turtles all the way down!"
— Hawking, 1988 A Brief History of Time

Traditions of Stipulation Define Disciplines. We find in West’s Encyclopedia of Law[**] the following characterization of stipulation as it is used in legal proceedings:
An agreement between attorneys that concerns business before a court and is designed to simplify or shorten litigation and save costs. During the course of a civil lawsuit, criminal proceeding, or any other type of litigation, the opposing attorneys may come to an agreement, foregoing further investigation, about certain "facts" and "issues". Such an agreement is called a stipulation.

From this conception of stipulation it is easy to construct parallels for almost any kind of research that does not or cannot push to some ultimate, incorrigible result. Within a discipline practitioners tend to pursue answers to questions arguably recognized as within the scope of their discipline, using methods arguably related to traditional methodologies. One cannot proceed within a discipline without some potential for recognition from others in that discipline that their undertaking is appropriate. Every graduate student learns early on how narrowly one must frame a research question for it to be acceptable to an advisor. (See Becher, T. Academic Tribes & Territories: the Cultures of the Disciplines. 1989.) See All Definition Ultimately Rests on Stipulation, i.e. Communal Agreement.

Of course, one can strike out on one’s own pursuing “gigantic truths” and risk possible self-delusion, uncompensated-for bias,and dismissal, should one's efforts, in the long run, not stand up to criticism from interested parties. Many famous discoverers have run this gauntlet and met with success, if only posthumously. (Many more of us console ourselves with advice from an ancient and also unremembered author: Pan metron ariston.)

But even well-established contexts of research have their own problems. Coordinated group activities, in general, are subject to tensions among authority, consensus and efficiency. Research problems frequently raise issues as to who decides procedures and goals, how much agreement among participants has to be obtained on these issues to come to a decision; and, how best to use the resources available for it.

The sticking point is this: such decision-types, i.e. those arbitrating authority, consensus and efficiency, may reiterate themselves for every decision consequently reached. This reiteration is often dismissed by invoking some tradition of stipulation contexts, e.g. budget limits, time and opportunity costs, political opposition from funding sources, diminishing returns on output, even researcher fatigue or boredom. (See The Fractalization of Social Enterprise)

Just as lawyers on opposing sides may stipulate evidence they have no hope of subverting, so do researchers in any field forego spending time and effort on pursuits that consume scarce resources with little promise of compensatory yield.

But What About Objectivity? Wouldn’t stipulation make it impossible?

In the early 1970’s I met a researcher whose speciality was disease etiology. Her interest was aroused by an apparent correlation between increased density of cancer cases and density of chemical manufacturers in certain neighborhoods of a large Eastern city. She obtained federal funding and began her investigations by interviewing people in those neighborhoods.

Two weeks into her interview schedule, she received a phone call at 3:00 A.M. The caller warned her not to continue the interviews; not even to come back in to the neighborhood. Otherwise, she would “end up with two broken legs.”

Being of a somewhat crusading spirit, she considered continuing with her research despite the phone call. Her husband, however, was not comfortable with her ignoring the threat. Little matter: one day later, while she was still weighing a decision, she received a phone call — this time at an appropriate hour — telling her that the funding for her research had been cancelled. No explanation was given.

No doubt from the research perspective of trying to see if there was a relationship between cancer victims and numbers of chemical plants, a set of conditions had been stipulated which impaired the objectivity of her research. The research was terminated before the experimenter’s intended procedures had been carried out. Lacking more information, we can speculate as to what the research-termination procedure was stipulated to be, although we do not know who had the power or authority to do it.

Objectivity depends on what the proposed object is. If all you want to do is stare through a tube to see pretty patterns, then a kaleidoscope will do as well as a telescope. Every procedure, or instrument employed in a procedure, can be questioned to what extent it creates as well as gathers “data.” Reliable instruments, stipulated as such, may permit reasonable stipulated outcomes, e.g. abridgments of otherwise lengthy procedures. (See Can Criminal or Immoral Behavior Be Dealt With Objectively?)

Living with False Assumptions

Never ASSUME, for when you ASSUME 

You make an ASS out of U and ME. 

-- Benny Hill
Like fat, sugar and other additives in our foods, the following “principles” are so deeply embedded in our culture that in most situations we unthinkingly fall back on them, although, under even casual consideration, we would find them far from certain. These principles are
The Principle of Command: To command is to control.
The Principle of Accepted Value: What we value, everyone should value.
The Principle of Objectivity: Facts are facts.
How do such principles control our thought processes?
