The study examines how demand characteristics bias emerges during a research interview, showing a participant adjusting responses to match perceived research expectations. Using a Japan-based case, the article documents the moment of explicit acknowledgment—“I thought I should give you good answers”—elicited through closing prompts. It analyzes the mechanism through demand characteristics bias alongside the Hawthorne effect and positioning theory, and argues for more reflexive methodologies and critical reassessment of research legitimacy.

Evidence of Demand Characteristics Bias in a Research Interview

Demand characteristics bias during the interview

Implications for research validity and reflexive methodology

The Electronic Journal for English as a Second Language “I Thought I Should Give You Good Answers”: Evidence of Demand Characteristics Bias in a Research Interview February 2026 – Volume 29, Number 4 [https://doi.org/10.55593/ej.29116s1](https://doi.org/10.55593/ej.29116s1) Takaaki Hiratsuka Ryukoku University, Japan <[takaakihiratsuka@gmail.com](takaakihiratsuka@gmail.com)> This article documents how ‘demand characteristics bias ’—participants’ tendency to harmonize responses with perceived research expectations—unfolded during a research interview. Drawing on a Japan-based study, I present explicit evidence of a participant unmistakably acknowledging that she adjusted her responses to provide what she believed the researcher wanted to hear, hence unveiling the ways research encounters can inadvertently elicit performative compliance rather than authentic responses. The participant’s candid admission—“I thought I should give you good answers”—surfaced during a closing prompt (“Is there anything else you want to share?), after which she continued to offer further revealing accounts. The analysis and discussion of this particular case brings together insights from demand characteristics bias, the Hawthorne effect, and positioning theory to account for the mechanisms through which research interactions influence participant responses. Implications include the need for more reflexive methodologies and a critical reconsideration of such research. Keywords: demand characteristics, qualitative methodology, research bias, interview method, Japan For nearly four decades, discourse surrounding Japan Exchange and Teaching (JET) program has produced consistent messages. Study after study and testimonial after testimonial have celebrated three key aspects of the program: (a) the motivational impact of JET foreign assistant language teachers (ALTs) on Japanese students, (b) their role in advancing intercultural exchange within communities, and (c) the program ’s contribution to Japan ’s diplomatic soft power. This consistency spans different researchers, participants, methodologies, and time periods—thereby amassing what appears to be robust evidence of the program ’s effectiveness (see Adachi et al., 1998; CLAIR, 2025; Estampador-Hughson, 2020; Johannes, 2012; McConnell, 2000; Metzgar, 2012, 2017; Roloff-Rothman, 2012; Tajino & Walker, 1998a, 1998b) . Nevertheless, this very consistency becomes troubling when weighed against the complex realities of educational implementation. My skepticism toward this uniformly positive portrait began during my own work as a local Japanese teacher of English in senior high schools, where I witnessed a far messier reality. Some ALTs were indeed inspiring professionals who transformed their students ’ relationship with English; others arrived woefully unprepared or found themselves entirely marginalized within Japanese school systems. Some students thrived in team-taught lessons by ALTs and JTEs, whereas others dismissed them as confusing or unhelpful for their examination-focused learning goals (see Hiratsuka, 2013, 2015a, 2017) . Despite this unevenness, published accounts have largely spotlighted stories of success while pushing aside and ignoring the voices of those whose experiences fell outside official aspirations (e.g., students, JTEs, and Japanese community members) (see Hiratsuka, 2022, 2023a, 2023b) . A recent interview brought this disconnect into sharp focus for me. A former student who had experienced ALT lessons—and who was participating in my study—devoted more than 30 minutes in her interview to offering positive assessments of her experiences. This was exactly the kind of narrative that dominates the existing literature. However, when I asked a closing prompt,“Is there anything you want to say before finishing the interview? Is there anything I should have asked during this interview?” everything changed. It became clear that her earlier responses exemplified the worki

FAQs

What is demand characteristics bias in this article?

It is participants’ tendency to align their answers with what they believe the research expects, producing performative rather than authentic responses.

How does the article show evidence of the bias?

The participant explicitly admits that she adjusted her responses to give “good answers,” especially after closing prompts that prompted further disclosure.

What theoretical lenses are used to explain how the interaction influences responses?

The discussion connects demand characteristics bias with the Hawthorne effect and positioning theory to account for the mechanisms at work.
