Explanation
This comic is titled "Personal Deficiency + Stats Knowledge = Super Powers." It shows a person dressed as a superhero (complete with mask and cape) bursting into a room full of people and triumphantly announcing, "Hahaha! I have lowered the average IQ of the entire room." The people in the room look dismayed and uncomfortable.
The joke is that knowing some basic statistics allows you to reframe a personal shortcoming as though it were an impressive feat. Having a low IQ is normally considered a disadvantage, but understanding the concept of averages lets this person boast about their ability to single-handedly drag down the mean IQ of any room they enter, as if it were a superpower. The humor lies in the absurd confidence with which a deficiency is presented as an achievement, and in the fact that this "power" is technically real but completely useless and unwanted.
The votey panel continues the gag with the same superhero character announcing, "The room is now 14% more ginger!" This extends the joke to another personal trait (red hair), suggesting this persons "superpower" is simply being a statistical outlier in whatever room they enter, and proudly announcing their impact on the rooms demographic averages.
