After two days at CASRO, I learned the following:
- When you use a 5 point or 7 point scale, you will get different answers
- When you label or don’t label scales, you will get different answers
- When you use a web survey vs a mobile survey, you will get different answers
- When you gamify a survey, you will get different answers
- (And from the good ol’ days) when you run the same survey on two different panels, you will get different answers
What are we to gain from all of this? Well, no matter what you do or how you do it, you will get different results on surveys every time. There’s just no way around it. What we HOPE is that the results won’t be contrary, but rather simply different in magnitude. That rank orders will remain generally similar, that hates will remain hates, and loves will remain loves. Indeed, if we are lucky enough to run a single study across a number of different methods or styles and get similar rank orders every time, it’s a good indication that the conclusions we’ve drawn are both reliable and valid. Heaven.
What this problem also suggests is that there is and can be no right answer. The only right answer is the one in the responder’s head and given that people can’t even adequately describe what is going on in their head, it seems that we will never know the right answer. What we can do is develop clear and specific research hypotheses, and match them up with clear and specific research designs. That is best way to create reliable and valid answers.
We may not know the exact right answer, but we can know a good answer.

Sentiment analysis is a very controversial subject with many people highly doubtful of the validity of the results. With that in mind, I have developed a set of rules that will allow you to ensure your data is scored with validity levels greater than 90%.
- Choose messages that are short. The shorter the better. Tweets are a perfect example as people generally make only one concise point that can’t be misconstrued. Longer messages simply introduce extraneous information that isn’t essential to the main message.
- Don’t collect data from blogs and forums where people may express their points in long, drawn out, overly verbose ways. These types of messages may include well described pros and cons, positives and negatives, and this only confuses things.
- Remove from your dataset any messages that incorporate unclear opinions or contradictory opinions. Obviously, the speaker isn’t sure of what they are speaking and so their opinion won’t be helpful.
- Remove from your dataset any messages that you aren’t sure how to score. Perhaps they contain emoticons you aren’t familiar with, slang that doesn’t make any sense, or grammatical errors that render the message not understandable.
Rather than worrying about ignoring important subsamples of people who have complicated opinions, people who associate themselves with subcultures, or the obvious skewing and biasing of results, simply focus on the parts of the data that you know will be correct. And there you go. Your sentiment analysis is 95% accurate. It doesn’t generalize to any population, but boy is it accurate!
– If you’re interested in a less sarcastic view of how accurate sentiment analysis, Seth Grimes is the expert in this field. Read here as he explains why validity scores can’t really be any better than 83%
Wait, was that a typo? Quantity over quality? Well, I meant what I said.
Question #1: What was the sample size of your last tracker? 30 per time frame? 50 per time frame? What about your last custom study? 300? 500?
Question #2: How many pages of questions and demos and cross-tabs did you flip through searching for any chi-square or t-test that was statistically significant? 100? 200?
Here’s the problem. We run ridiculously long surveys with far too few participants per test cell and we are ok with searching through far too many Type 2 errors.
Here’s the solution. Put your money into large sample sizes and not into question topic after question topic. Focus on sample sizes within demographic groups rather than questions with 4 or 8 people per cell. Trade variety of questions for reliability of results. Trade overly long surveys for properly sampled cells. Trade breadth of topics for validity of individual questions. Take money away from more and more questions and put it directly into more and more validity and reliability. Radical.
Please comment below. What was the sample size of your last study and what was the sample size within many of the cells?

1) You can tell how valid a sentiment scoring system is by evaluating as few as 20 records
2) You can accurately judge validity by examining the originally assigned score and deciding if you agree with it
3) If data for one brand is valid, data for all the brands are probably valid as well
4) You can judge validity by checking twitter data as it is the lowest common denominator
5) If the system is based on natural language processing, you know the sentiment is valid
6) If the sentiment scoring is manual, you know it’s perfectly valid.

I love shopping for toilet paper. It is one of the most exhilarating parts of my life. It’s extremely rewarding to choose between the 12 pack and the 24 pack knowing that my family won’t have to worry about running out mid-wipe for at least a week or two. I love taking the extra time to choose between extra soft and supreme soft knowing that it brings with it the responsibility of selecting the most appropriate texture for my loved ones’ bottoms. And making the important decision between 2 ply and 3 ply means that I’ve have the joy of taking charge of cleaning up those nasty messes that no one wants to talk about.
I truly enjoy and look forward to each of these decisions because it is fun to consider the myriad options and know that I have succeeded in bringing joy to my family.
Unfortunately, even though the process of shopping for toilet paper is extremely fun, the process of answering surveys about toilet paper shopping isn’t. I just wish there was some way to make answering toilet paper surveys more fun, like a game, like it is in real life.
Because I know if the survey taking experience emulated my real life experience, my survey answers would be more valid. Don’t you agree?
Here’s your task. Read the following list of tasks and identify which ones are useless to brands and clients: – Watching how people interact with and actually use a product – Listening to how people talk about products with their peers – Learning which features people use to convince other consumers – Learning how consumers convince others to use a product
- Observing facial expressions of disgust and shame and love and peace – Watching for passion and complacency
Your second task: Make a list of all of the research methods that are error-free, risk-free and always give valid and reliable results.
There may be no perfect research method but there’s definitely a place for focus groups.
It’s pretty easy to write a questionnaire and know exactly how the flow should go. It’s also pretty easy to predict what the answers will be and how they will distribute. Simply ask people why they buy stuff and people will tell you why they buy stuff. Or will they?
What is the common denominator behind all of these words? Each word describes a psychological process wherein people respond to questions for reasons that are not known even to them. No matter how hard people protest, they are easily swayed by the opinions of others, the presence of others, and the place of others.
Yet, when we write surveys or analyze, we often throw these heavily researched truths out the window and ponder at the incongruencies of answers. Why did someone say they don’t buy poptarts in this question but they DO buy poptarts in this question?
It’s pretty easy to assume you’re smarter than everyone else when you see all the “mistakes” and “sloppy logic” made by responders on surveys. It’s also pretty easy to ignore that you make these same “mistakes” all the time too.
As market researchers, and particularly those researchers who have a background in psychology, we need to make sure we keep it top of mind that no matter how hard people try, they aren’t always rational.
Think outside the Vulcan box when designing surveys. Forget all you know about the brand and the category, and what the right answers should be. Think like a confused, late for work, multi-tasking person with a 352 item to-do list and dog poop on the living room floor.
Realize that you aren’t in fact smarter than everyone else and those illogical survey responses are actually real human behaviour. There’s more to human behaviour than just simple logic.
