Advantages of operational definitions:

There is a great deal of controversy among philosophers about theimplications of this type of research. Proponents of RTM are, ofcourse, entirely happy with the idea that the scientific theories ofwhat birds are doing can be taken at face value. Other philosophersmaintain that if the scientific theories say that birds are computingan algorithm for determining a caching strategy, then this can only beread as a façon de parler. Still others will grant that animalshave representations but go on to claim that these representation areof a lesser status, not to be confused with concepts (Brandom 1994,2000, McDowell 1994).

Limitations of operational definitions:

The model is an image of how we expect the concepts to covary in the empirical world.

The scale of measurement depends upon the operational definition.

And if truth is relative, then there is no singleshared definite aim for any given assertion (see MacFarlane2014: ch. 12 for a discussion). The relativists however, couldrespond that truth is relative to a group (conceptual scheme,framework) and they take speakers to be aiming a truth relative tothe scheme that they and their interlocutors are presumed toshare. The difficulty with this approach is that it seems to makecommunication across frameworks impossible.

4.5 Construct operational definitions of the concepts in the model.

Plato’s argument, as it stands, appears to be damaging onlyif we assume that Protagoras, at least implicitly, is committed to theuniversal or objective truth of relativism. On this view, Plato begsthe question on behalf of an absolutist conception of truth (Burnyeat1976a: 44). Protagoras, the relativists counter, could indeed acceptthat his own doctrine is false for those who acceptabsolutism but continue believing that his doctrine is truefor him. He could also try to persuade others to become the sortof thinker for whom relativism is true without being entangled inself-contradiction. Such an effort at persuasions, however, couldinvolve Protagoras in a performative contradiction as the relativistcannot assume that her arguments are good for persuadingothers. Ordinarily, the very act of defending a philosophical positioncommits us to the dialectical move of attempting to convince ourinterlocutors of the superior value of what we are arguingfor. The relativist cannot make such a commitment and therefore hisattempts to persuade others to accept his position may bepragmatically self-refuting. The relativist can avoid the standardcharge of self-refutation by accepting that relativism cannot beproven true in any non-relative sense—viz., thatrelativism itself as a philosophical position is at best true onlyrelative to a cultural or historical context and therefore could befalse in other frameworks or cultures. But such an admission willundermine the relativist’s attempt to convince others of herposition, for the very act of argumentation, as it is commonlyunderstood, is an attempt to convince those who disagree with us ofthe falsehood of their position. In other words, if Protagoras reallybelieves in relativism why would he bother to argue for it?

Examples of directly measured concepts measured by one variable include age and gender.
Measured operational definitions describe how referents of a term are measured.

Difficult Concepts: Research Hypotheses vs

Perhaps the most influential discussion of concepts in relation to thenativism/empiricism debate is Jerry Fodor's (1975, 1981) argument forthe claim that virtually all lexical concepts are innate. Fodor(1975) argued that there are theoretical problems with all models ofconcept learning in that all such models treat concept learning ashypothesis testing. The problem is that the correct hypothesisinvariably employs the very concept to be learned and hence theconcept has to be available to a learner prior to the learning takingplace. In his (1981), Fodor developed this argument by allowing thatcomplex concepts (and only complex concepts) can be learned in thatthey can be assembled from their constituents during the learningprocess. He went on to argue that lexical concepts lack semanticstructure and consequently that virtually all lexical concepts must beinnate—a position known as . Fodor's arguments have had a great deal of influence ondebates about nativism and concept learning, especially amongstcognitive scientists. Few if any have endorsed Fodor's radicalconclusions, but many have shaped their views of cognitive developmentat least in part in response to Fodor's arguments (Jackendoff 1989,Levin & Pinker 1991, Spelke & Tsivkin 2001, Carey 2009). AndFodor has convinced many that primitive concepts are in principleunlearnable (see, e.g., Pinker 2007). Fodor's arguments for thisconclusion, however, can be challenged in a number of ways. The mostdirect way to challenge it is to construct an account of what it is tolearn a primitive concept and to show that it is immune to Fodor'schallenges (Margolis 1998, Laurence & Margolis 2002, Carey2009).

In a study, the authors will give the operational definition of the variable that they think is best suited to their needs.

Theoretical | Definition of Theoretical by Merriam-Webster

The typical allopathic clinical approach to autoimmune disorders focuses on the management of symptoms with various anti-inflammatory medications and often the use of chemotherapeutics, and very potent immunosuppressive agents with nasty potential side effects such as leukemia and lymphoma.2 While these approaches admittedly can provide substantial symptomatic relief to the patient, they do not get to the cause of these conditions, and some research suggests that these approaches may result in a furthering of the pathological process. However, modern research into autoimmune phenomena suggests that radically different approaches may be required to reverse the above-cited trends, including a strong emphasis on very early detection with predictive autoantibodies, a focus on optimizing gastrointestinal mucosal immune function and the microbiome, eradication of infectious agent triggers with antimicrobial therapy, and even the seemingly bizarre use of parasitic agents therapeutically. Some of these concepts have a long history in naturopathic and functional models of medicine, but now are emerging as hot areas of emphasis in mainstream medical research journals and investigative communities in immunology.
