The logic of methodological pluralism argues that prediction and explanation are, after all, not the only legitimate goals of science.(26) Moreover, as we have seen, there are profound methodological problems associated with the empirical confirmability (disconfirmability) of models which assume classical rationality and stable preferences.
NLD thus provides an uncontrived counterexample to the methodological claim that explanatory power, simplicity, and confirmability (truth) do not go together, as well as to the associated metaphysical intuition that complex systems cannot be faithfully represented by simple theories.
Third, and with the exception of Graumann and a few rare allusions, there is little cross-fertilization of ideas in other chapters let alone contents, and readers will sorely miss an editors' epilogue where underlying principles (perhaps perceived causality and confirmability, to name but two) could have creatively welded these very differing contributions together.
Both quantitative and qualitative research have "truth value"--quantitative research with its applicability, consistency, and neutrality, and qualitative research with its credibility, transferability, dependability, and confirmability |15, 145~.
Attorneys could battle at length over the confirmability of any plan.
Trustworthiness of the qualitative results was considered using the principles of: confirmability (i.e.
Trustworthiness was established through credibility, transferability, dependability, and confirmability (Lincoln & Guba, 1985).
Word clouds were created for individual interviews and for all the interviews collectively to display the participants' emphasis on certain words depicting their intentions, thus demonstrating plausibility, confirmability and sturdiness of analysis.
Trustworthiness was sought based on credibility, transferability, dependability, and confirmability (Creswell, 2013).
However, the trustworthiness of this study is further strengthened by the strategies of: credibility, transferability, dependability and confirmability.
Given the qualitative paradigm of this study, we established trustworthiness by using Lincoln and Guba's (1985) guidelines for credibility, transferability, dependability, and confirmability. We maintained credibility through triangulation and frequent peer debrief, transferability through thick descriptions and wide inclusion of data.
To ensure of this study's rigor, credibility, dependability, transferability, and confirmability were considered.(23) Conducting in-depth interviews at various times and places convenient to the participants, choosing the participants with the consideration of maximum variation and verifying the extracted codes by the participants were in line with ensuring credibility.
