Patton Uses The Term Preponderance Of Evidence To Describe The Bes

Patton uses the term “preponderance of evidence” to describe the “best fit” between the data a researcher gathers and the patterns and conclusions he or she draws, as quoted by Merriam & Tisdell (2016, p. 249). This term is borrowed from courtroom procedure, where it is the standard of proof used in noncriminal cases. In the legal context, a judge or jury must find that a given fact is proven if, based on the evidence provided, it is more likely than not (or greater than 50% likelihood) to be true.

In qualitative research, the validation and credibility of findings are crucial for ensuring that the conclusions accurately reflect the phenomena under investigation. The question arises whether the legal standard of “preponderance of evidence” is appropriate for validating qualitative research. This evaluation requires a nuanced understanding of the differences between legal proof and scientific rigor, especially in the context of qualitative methodologies.

The “preponderance of evidence” standard implies that the evidence supporting a particular conclusion must simply be more convincing or more probable than alternative explanations. This standard aligns with the interpretative nature of qualitative research, which often involves synthesizing complex, contextualized data from interviews, observations, and textual analysis. Unlike quantitative research, which relies heavily on statistical significance and numerical measures, qualitative research emphasizes depth, meaning, and richness of understanding.

In support of using the “preponderance of evidence” standard in qualitative research, it can be argued that this threshold recognizes the inherently interpretive and context-dependent nature of qualitative data. For example, Lincoln and Guba (1985) propos that trustworthiness criteria such as credibility, transferability, dependability, and confirmability are essential for validating qualitative findings. These criteria support the notion that evidence must convincingly substantiate interpretations, aligning with the idea that a conclusion should be more likely than not to be true based on the accumulated evidence.

However, critics might contend that the “preponderance of evidence” standard, borrowed from legal contexts, may oversimplify the assignment of truth to qualitative findings. Unlike courts, which seek an objective threshold for guilt or innocence, qualitative research often grapples with subjective meanings, multiple realities, and transferability rather than absolute truth. Ragin (1994) points out that qualitative validity involves contextually grounded and interpretive considerations that cannot always be reduced to a probabilistic threshold. Moreover, reliance on a “more likely than not” standard may risk overconfidence in certain interpretations that lack sufficient rigor or corroboration, particularly in studies where researcher bias or limited data could distort the findings.

A compelling argument against applying the legal standard is that qualitative research aims for trustworthiness rather than definitive proof. Guba and Lincoln (1989) argue that establishing trustworthiness involves demonstrating that interpretations are well-supported by data, transparent, and consistent across different contexts, rather than simply “more likely than not.” This perspective suggests that validation involves multiple lines of evidence, reflective consistency, and researcher reflexivity, rather than a singular probabilistic threshold.

In practical terms, the appropriateness of the “preponderance of evidence” for qualitative research depends partly on the research purpose and context. For exploratory or descriptive studies, where the goal is to generate plausible, well-supported understandings, this standard might suffice. Conversely, for studies aiming at theory development or explanatory claims, higher standards—such as triangulation, member checking, and thick description—are necessary to substantiate claims convincingly beyond a mere “more likely than not.”

In conclusion, the use of the “preponderance of evidence” standard in qualitative research can be both appropriate and problematic. It acknowledges the interpretive and subjective aspects of qualitative data, aligning with criteria for trustworthiness and plausibility. However, it risks oversimplification if used as the sole measure of validation, potentially discounting the nuanced, context-dependent validation strategies integral to qualitative inquiry. Therefore, qualitative researchers should employ this standard judiciously, complementing it with comprehensive validation techniques to enhance the credibility and trustworthiness of their findings.

The question of whether the "preponderance of evidence" is an appropriate standard for validating qualitative research hinges on understanding the fundamental differences between qualitative and quantitative methodologies, as well as the core purposes of validation within each paradigm. The term, borrowed from legal proceedings, signifies that a claim or conclusion can be considered proven if it is more likely than not—that is, with a probability exceeding 50%. While this standard works within the judicial system where definitive proof is required to establish guilt or innocence, applying it directly to qualitative research warrants careful scrutiny and contextual adaptation.

Qualitative research prioritizes depth, context, and meaning over numerical generalizability. Rather than establishing truth through statistical significance, it seeks to generate credible, trustworthy interpretations of complex social phenomena. Lincoln and Guba (1985) articulated core trustworthiness criteria—credibility, transferability, dependability, and confirmability—that serve as benchmarks for assessing the rigor of qualitative findings. These criteria emphasize thick description, persistent observation, triangulation, member checking, and reflexivity, reflecting a multifaceted approach to validation that is rooted in transparency and contextual appropriateness rather than probabilistic thresholds.

Proponents argue that the “preponderance of evidence” standard aligns with the interpretive nature of qualitative research. Since qualitative findings are often subjective and context-dependent, the idea that evidence should simply be more convincing than alternative explanations can be seen as a pragmatic and realistic validation approach. For example, Lincoln and Guba (1985) suggested that if the evidence convincingly supports a particular interpretation—meaning that it is more plausible and better grounded in data—then the conclusion can be deemed trustworthy. In this sense, the “more likely than not” standard recognizes the inherent uncertainties and interpretive strategies involved in qualitative inquiry.

However, critics contend that this standard may inadequately address the nuanced and often subjective process of qualitative validation. Unlike the legal context, where a clear-cut probabilistic threshold establishes guilt or innocence, qualitative research deals with multiple realities and perspectives. Ragin (1994) emphasized that validation in qualitative research involves constructing a coherent, evidence-based narrative that withstands scrutiny, rather than merely surpassing a probabilistic benchmark. Relying solely on “more likely than not” can risk oversimplifying or overconfidence in interpretations that lack corroboration or are influenced by researcher bias.

Furthermore, qualitative validation often involves multiple strategies designed to enhance credibility and dependability. Techniques such as triangulation—using multiple data sources or methods—contribute to a robust evidentiary base that strengthens confidence in findings (Flick, 2018). Member checking, where participants verify interpretations, and rich, detailed descriptions provide transparency and contextual grounding. These strategies collectively move beyond a simple probabilistic threshold, emphasizing instead the comprehensive and contextual validation of interpretations.

In considering whether the “preponderance of evidence” is suitable for qualitative validation, it is essential to recognize that qualitative research aims for trustworthiness rather than absolute proof. As Guba and Lincoln (1989) argue, validity in qualitative studies is contextually grounded and achieved through a convergence of evidence, consistency, and researcher reflexivity. Applying a strict “more likely than not” rule may be too narrow, overlooking the complex, interpretive, and narrative nature of qualitative data. It could lead to overconfidence in findings that have not been sufficiently scrutinized or corroborated through multiple validation techniques.

Therefore, while the “preponderance of evidence” standard may serve as a useful heuristic—prompting researchers to substantiate claims convincingly—it should not be the sole criterion for validation in qualitative research. Instead, researchers should complement this approach with established validation techniques, including triangulation, member checking, audit trails, and peer debriefing. These strategies collectively ensure that interpretations are credible, well-supported, and transparent. By doing so, qualitative researchers can uphold the rigor and trustworthiness of their findings, consistent with the epistemological and methodological principles that underpin qualitative inquiry.
