I will be saying this till I'm blue in the face - linguistics is a great tool to impact marketing, branding and segmentation. What you say - more specifically how you say it, describes a lot about your own personality. This article I found suggests that just by capturing 50 tweets companies can analyze and predict what products or services you are more likely to buy.
But how? Let me describe a little bit of the science behind tweet psychology.
"The quick foxed jumped over the mean lazy brown dog."
Ok. Now, you ready? This is going to be very, very, very hard. Pay attention. Please keep reading this sentence a bit, maybe this word "Pneumonoultramicroscopicsilicovolcanoconiosis" - I just need you to get further down this paragraph so you can't see the first sentence. GOOD - Don't look up! Now, how many non-verb/subject/adv/adj words were in the sentence about the fox from above. If you said 3, you're a super-freak - No, JK, you are normal however the point of this exercise is to demonstrate the transient nature of pronouns (and all other words that aren't verbs, adjs, advs or nouns for that matter). Your brain is programmed to strip away this non-essential information like meat from a bone. Pronouns and all of these filler words (because, that, we, up, therefore, she, besides, however) are parsed out of normal conversation and forgotten. Your brain remembers the: Who, What, Where, When and Why - the meat.
When in doubt, follow the crazy people
Pronouns and Nouns/Verbs/Adj/etc are filed in two completely different sections of the brain. One way to prove this is to study the effects of brain damage and speech. There are actually two different types of studied medical injuries that are a result of brain damage in two separate parts of the brain - the two injuries would speak thusly:
“You know, that stuff where those things move up and down and even though things come out”
“Mary knows keyboard keys help people print documents”
You'll notice that Bud Abbot has a hard time using anything but "filler words" (pronouns, prepositions) while Lou Costello can't seem to find one single filler word - he only uses proper names and verbs. This is because Bud Abbot has received damage to the Nouns/Verbs/Adj/etc processing center of his brain while Lou Costello has received damage to his filler "social words" processing center.
Twitter pronouns are key to marketing
So, now we agree that filler words, compared to nouns and verbs, are contained in different boxes in the mind? Would it surprise you to hear that pronouns and fillers are kept in the very front, youngest part of the brain - the "social" box? (which makes sense as they are social referents). Nope? Moving right along, how you use these social referents tells us a lot about how you live in a social world. For example, do you use the "I" pronoun more than the "we" pronoun? DID YOU KNOW - men use the pronoun "I" slightly more often then women, while women use the pronouns "You /He/She" slightly more often than men.
So users that tweet "s/he" more often and use causal words (because, cause, on account of) are more likely to be rational, logical, social thinkers - who would obviously gravitate to a certain kind of product or experience. Now the game is over. BAM, once the company has you profiled they can market to you more effectively.
Research has already shown that these traits link to buying behaviour. Agreeable people prefer Pepsi to Coke and if you link your product messages to excitement and adventure, it will appeal to the extroverts.
All well and good, but how can brands find out the psychological profiles of their potential customers? After all, no-one is going to go through a long personality test to give marketers the information they need to harass them.
The answer is via social media, specifically Twitter. IBM’s research has used software to analyse three months data from 90m Twitter users, matching the words people use against their values and needs. It took just 50 tweets to get a reasonable match for their personality and a very good fit from 200.
