Your favorite coffee shop has introduced a new variety. As you stand in line for your usual order, a positively delightful staff member offers you a free sample of the new brew. They look on, eagerly awaiting your response as you give it a try.

And you hate it.

It's the nastiest drink you've tried in ages. Yet somehow, your head nods in grimaced approval. You smile, anxious to please the lovely staff member. Is that really an "mmmm" sound you're making?

Armed with its dodgy customer research data, the coffee shop thinks it has a certain hit on its hands. But you know you will never less this product pass your lips again as long as you live.

Maybe your business has already learned this lesson the hard way. But the fact is, when you conduct market research, there's every chance your research participants will not be telling you the truth.

Are they all barefaced liars?

Are these participants out to deliberately lead your business astray? Do they trick innocent researchers just for fun? Of course, that's not the case. When research respondents start telling you fibs, the problem often lies with what you're doing.

The chances are your survey, focus group or research process has unwittingly tripped one of these five big fib-triggers.

So, what are the biggest fib-triggers that you should avoid in your research?

1. Leading questions and the desire to please

The number one biggest fib trigger of all is not borne from a desire to mislead, but a well-meant desire to please.

Just as you grimaced an "mmmm" to please that lovely coffee shop assistant as they watched you, so your research participants will try to please you by giving you the "right answer" to your question.

They want to make you happy. If they think they know where your question is going, then they'll tell you what you want to hear. That is why it is so important to ensure that the questions you ask during the research process are not leading them towards a specific answer or your desired outcome.

For example, "Do you think our improvements to the café have paid off?" is a leading question. You are clearly revealing that your intent, that are looking for re-assurance that your efforts have been worthwhile. By asking such a leading question people will want to please you by giving you the answer you clearly seek.

"How would you rate the caf's decor?" is a far more balanced question. Just be prepared to accept that their view may differ from yours!

2. Don't make it personal

Keep it professional, keep your distance and don't let personal connections influence the out come of your research.

Your friends and family are often your biggest fans. So, these are the wrong people to be approaching for an objective view about your business and about new ideas.

They are likely to give your most hare-brained schemes the benefit of the doubt. They will also feel under pressure to be nice and positive, when it is a hard dose of objective realism that you are really seeking.
