For as long as we can remember we’ve been hearing that old saying, “a picture is worth a thousand words.” Despite how cliche it sounds nowadays, and how much we cringe at the very mentioning of this over used quote, it still holds true to this day. People use pictures in their arguments because they not only convey a treasure chest of information in a rather simple fashion, but they also convey this information in a very different way. Pictures allow an author to come at an argument at different directions, and as a result what they are writing feels more well rounded. For example, I could be writing an argument about why not to buy a Snuggie. I could go on and on about how all you need is a blanket or a robe, and a Snuggie is just an unnecessary thing to have in general. Soon enough, my reader will become fatigued from reading my sophisticated words and carefully constructed sentences on the matter and there is a good chance that the reader may not get through the whole argument. Information overload perhaps? Now, that’s where I would throw in this picture. Most readers these days will think “Look! Something that isn’t words!” and instantly gravitate towards it. Pictures tend to convey information much simpler and easier to understand than a group of sentences tends to. One could make the claim that a tendency towards pictures is something well ingrained into human nature. Humans had been telling stories with pictures for tens of thousands of years; cave paintings have been around forever after all. Writing is a very new innovation by comparison and as a result may take a back seat to pictures deep in our consciousness.
Also, as evidenced here, pictures tend to be funnier than words, and who doesn’t love a good laugh?
