About Keirsey InFlow™ Survey Methodology.
Keirsey has been a trusted name in public research surveys for more than 30 years. Our InFlow™ methodology uses a high volume "river" sampling technique for surveys which insures unique responses for high integrity as well as fast turn-around.
There are no "professional survey takers" participating in order to earn rewards. InFlow™ allows us to obtain valid results with demographic integrity in a fast and efficient manner.
Because our respondents are not paid or otherwise incented to complete surveys, our results assure the highest integrity of data. No one is trying to "game" the survey in order to earn a reward, which leads to potential quality of data issues.
