Research Methods: Biases in Research - Common Method Bias
Monday Feb 14, 2022
Monday Feb 14, 2022
Welcome! Today we talk about a very important bias - the common method bias. It can happen that your research method itself, e.g. your questionnaire, creates a skewness in your answers. For instance, if your Likert scales have different font sizes or if the checkboxes on your Likert have different sizes, you may prime your respondents and (un)internationally force them to select a specific answer option.
In this episode, I explain how the bias appears, how to avoid it, and how to check whether your study contains a common method bias. Enjoy!

Research Methods: Biases in Research - Response Bias
Monday Feb 07, 2022
Monday Feb 07, 2022
Welcome! Last time we talked about the non-response bias. Today, we talk about the opposite - the response bias. Unfortunately, some people are motivated to participate in a survey because of, e.g. their anger or love. Angry customers are always ready to share their experience, whereas those who are satisfied are indifferent or postpone your survey. Your family members are always responding to all your surveys (because they love you). Yet, being unconsciously obliged to respond, they are not obliged to tell truth or even invest efforts. Thus, those who respond may skew your results even more than those who ignore your survey because of e.g. bad design. It is interesting, isn't it?
Enjoy the new episode!

Research Methods: Biases in Research - Non-Response Bias
Monday Jan 31, 2022
Monday Jan 31, 2022
Morning! Today I talk about one of the most important biases in survey research - the non-response bias. I present you an explanation, some examples, as well as I give you some ideas about how to test for the non-response bias.
Enjoy!

Research Methods: Biases in Research - Sample Selection Bias
Monday Jan 24, 2022
Monday Jan 24, 2022
I think we are slowly approximating the end of the topic of biases. No, please do not think, the biases are over - a friend and colleague of mine Professor Ganna Pogrebna wrote a book on biases in research and, believe me, there are many more. So feel free to google this book or write in comments if you haven't managed to find it. In this podcast, I mentioned only the main biases I encountered during my research.
Today, we talk about sample selection bias. It is dangerous in research but even more dangerous is this bias in politics when election polls are conducted. Listen carefully and try to avoid this bias in your research.
Good luck!

Research Methods: Biases in Research - Omitted Variable Bias
Monday Jan 17, 2022
Monday Jan 17, 2022
Welcome to my new podcast episode. Today, I talk about the "omitted variable bias". This bias is one of the most impactful for your research and, unfortunately, there is no universal cure apart from reading as much as you can. Of course, some researchers would argue that this is not a bias but a "normal theory development" - we find a relationship that we cannot explain. And this motivates us to look further until we find the "missing variable". I would agree if we talk about new phenomena. Yet, if a phenomenon has already been investigated and an important variable is not included because of not knowing about this research or with intent, then we talk about the omitted variable bias.
By the way, have you ever thought about it: many populist politicians use the omitted variable bias exactly to draw attention to the wrong relationships and "somehow forget" to report the true reasons for the issue?
Enjoy!

Research Methods: Biases in Research - Wording Bias
Monday Jan 10, 2022
Monday Jan 10, 2022
Today, we talk about wording bias. Doesn't matter how you ask your question, you influence the perception of the respondent through your words. "Are you satisfied with our services?" implies satisfaction. "In how much are you satisfied or dissatisfied with our services?" is better, although there might be some priming through the "satisfied" used first. "Isn't it exactly what you wanted to have?" is a highly skewing question since the answer "No" would make the person feel uncomfortable or even evoke the feeling of cognitive dissonance or guilt.
In this episode, I give some hints on how to avoid or mitigate wording bias. Enjoy, like, and subscribe, if you are passionate about research.

Research Methods: Biases in Research - Question Order Bias
Monday Jan 03, 2022
Monday Jan 03, 2022
Hello in the New Year!
I hope you had a niche Holidays time and now you are ready to work on your research again! Today, I introduce a topic on the question order bias. As you as a researcher are responsible for the question order, this bias is a researcher bias. I explain how and why it appears as well as I give some ideas on how to eliminate (or at least mitigate) this bias. Enjoy and feel free to subscribe and comment!

Research Methods: Biases in Research - Culture Bias
Monday Dec 27, 2021
Monday Dec 27, 2021
This week, we talk about cultural bias. This bias is very manifold, and I talk only about a few aspects of this bias. If you want to know more, you will need to study literature in this regard. I hope that some examples from my research may help you avoid similar mistakes in your future studies.
Good luck and Enjoy!

Research Methods: Biases in Research - Confirmation Bias
Monday Dec 20, 2021
Monday Dec 20, 2021
Today, we start talking about biases on the side of the researcher. The topic of our today's episode is the "confirmation bias". This bias appears if a researcher instead of trying to reject his or her hypothesis tries to support it. Apart from being a wrong scientific approach, a "belief" of a researcher may impact his or her formulation of questions or design of the experiment. For instance, the questions which could reject a hypothesis are forgotten/omitted. Listen more about the bias in the current episode!

Research Methods: Biases in Research - Recall Bias
Monday Dec 13, 2021
Monday Dec 13, 2021
Welcome! How did you feel today? How did you feel last month? Asking such questions evoke the recall bias - instead of relying on (real) memory, we "recall", i.e. we construct the memory. Here, our current feelings, intuition, or state may skew our answers. This bias is called "recall bias". More about this bias in the current episode.
Enjoy!
Faithfully yours
