The major benefits of infographics is that they are a visual medium, this is hugely important as it has been found repeatedly that people both understand and retain information better when it is presented in visual form. In some figures up to 80%. (Mc Canless, 2010)
It has also been found that people usually read information online by skimming the text rather than reading in detail meaning infographics which allow users to skim through information are both more appealing and more likely to get people to read them. (Smiciklas, 2012)
All of this means they can be a great alternative to posters or papers when they are used well.
They can also be used for academic conferences you may attend in the future.
