What Are The Advantages and Disadvantages of Interviews In Research?

Interviews are a key component of research methodology because they include narratives and insights that may not be captured by quantitative data alone. However, like with any methodology, qualitative as well as quantitative methods have pros and cons of their own, influencing the field of research in subtle ways.

This study explores interview-based research, highlighting the advantages and disadvantages that researchers must manage to extract significant and genuine results. When looking for professional direction on how to structure research initiatives and weigh the pros and drawbacks of qualitative and quantitative research in interviews, Research Proposal Help might be a valuable resource.

What are Interviews, and Why Is Research Important While Conducting Interviews?

Interviews are planned discussions between an interviewee and a researcher to obtain data, viewpoints, and ideas on a certain subject. These exchanges can be focus groups or interviews that are unstructured, semi-structured, or organised. Research is important in interviews because it might provide subtle information that quantitative approaches might miss. Through interviews, participants can express their ideas, feelings, and experiences, leading to a deeper comprehension of intricate phenomena.

The complexities of human behaviour, reasons, and viewpoints can be explored by researchers using strategic inquiry and active listening. The thorough perspective obtained via interviews enhances the research process by offering a qualitative depth that balances quantitative data. Interviews are a vital tool in the researcher’s toolbox because they act as a tool that bridges the separation between raw data and useful insights.

Four Interview Formats That Demands A Thorough Research

From structured and unstructured interviews to focus group interview advantages and disadvantages the following list describes each one in brief so that researchers may get an idea of which interview format they should opt for in the future!

1.    Structured Interviews

Goal: Using a methodical and uniform strategy to collect particular data.

Research Application: Data on predefined variables are collected in quantitative research to facilitate statistical analysis and comparison.

Benefits Conformity and Equivalency: Consistent data collection is ensured by standardised questions, making comparison and quantitative evaluation simple.

Negative Aspect Restricted Adaptability: Because the tight structure limits the study of unexpected or complex reactions, it is possible to miss important findings.

2.    Unstructured Interviews

Goal: Investigative and extensive comprehension of participant viewpoints.

Research Application: Frequently used in qualitative research to produce rich, descriptive data and unearth complex insights.

Benefits Thorough Investigation: Enables open-ended inquiry, producing rich qualitative data and promoting a thorough grasp of participant viewpoints.

Negative Aspect Variability in Data: Inconsistent data quality due to a lack of structure might make it difficult to properly identify and evaluate.

3.    Focus Group Interviews

Goal: The goal of group interaction is to provoke conversation and expose different points of view.

Research Application: Offers a deeper comprehension of the research issue by examining shared experiences, viewpoints, and interactions among participants in qualitative research.

Benefits Various Viewpoints: Promotes group interaction by offering a variety of viewpoints and pushing members to build on each other’s ideas.

The Negative Aspect is Collaboration: the responses can be influenced by dominant voices or groupthink, therefore effective facilitation is needed to keep the conversation balanced.

4.    Behavioural Interviews

Goal: The goal is to evaluate previous behaviour as a predictor of performance or reaction in the future.

Research Application: Frequently employed in psychological and organisational research to comprehend decision-making, behaviour patterns, and reactions to particular circumstances.

Benefits Forecasting Understandings: Offers insightful information for predictive analysis by analysing historical behaviour as a predictor of future decisions or behaviours.

Negative aspect is Limited Context: Ignores the impact of situational settings or outside influences in favour of focusing on behaviour alone.

Explore The Advantage and Disadvantage of Qualitative and Quantitative Research In Interviews


  • Rich Qualitative Data: The capacity of interviews to produce detailed, rich data is one of its main benefits, especially in qualitative research. Researchers can examine complex viewpoints, feelings, and experiences that may be difficult for quantitative techniques to fully represent by using qualitative approaches.
  • Statistical Generalisation: It is a feature of quantitative research that enables researchers to make findings that apply to a larger population. This is very helpful when trying to establish relationships or make predictions.
  • Flexibility and Adaptability: Interviews allow for customization of questions and conversational modifications in response to participant responses. This flexibility enables researchers to investigate novel ideas and go further into topics that might not have been planned for in the original study design.
  • In-Depth Investigation: A deeper examination of the research issue is made possible by both qualitative and quantitative interviews. By going beyond the participant’s obvious answers, researchers can acquire a thorough grasp of their motives, ideas, and environment.
  • Developing Connection and Trust: Interviews are a common tool used to help participants and researchers develop a trustworthy relationship. In-person or even virtual conversations foster a personal connection that encourages people to communicate more authentically and openly.


  • Subjectivity and Bias: Interviews are subjective, which increases the possibility of bias, especially in qualitative research. The assessments of the member and the specialist might affect the information accumulated, which could think twice about the discoveries’ objectivity.
  • Resource-intensive: Interviewing can require a ton of time, cash, and assets, especially about inside and out or long-haul interviews. This could restrict the scope of the study or make handling big sample volumes more difficult.
  • Interviewer Influence: A questioner’s presence can influence a member’s responses. Social attractiveness inclination is a typical concern that could influence the validity of the information since it permits members to give answers they accept to be socially satisfactory.


The benefits and drawbacks of using interviews in research show how the formal limitations of quantitative methods and the richness of qualitative insights interact. Interviews provide rich tales that quantitative data could miss, making them an invaluable tool for probing into the complexities of human lives.

However, due to their subjective nature, interviews present difficulties with standardisation and generalisation as well as possible prejudices. To effectively conquer this, researchers must take a deliberate strategy and carefully combine the advantages of both qualitative and quantitative methodologies.
