What is triangulation in social research?

Triangulation in social research is a technique to increase credibility of research outcomes. Borrowed from navigational and land surveying techniques, it aims to overcome biases in single method, researchers, data sets and/or theories.

There are 4 types of triangulation:

  1. Methodological – two or more methods are used to collect data
  2. Data – two or more different data sets
  3. Researcher – two or more researchers investigate
  4. Theoretical – two or more theories approach the often described as a way of ensuring some form of ‘truth’ in research results. This is one reason to use triangulation, but another is to intentionally draw out some of the differences

As an anthropologist I think we constantly aim to reduce the influence of bias in research we do. A competent, self-aware anthropologist is very good at observing phenomena from multiple viewpoints. Of course we can’t always overcome our own biases,  so designing your research (and synthesis) with triangulation in mind can contribute to overall outcomes.
