If you read Simler and Hanson's book
The Elephant in the Brain: Hidden Motives in Everyday Life, you're going to have to get introspective (because you can't go around calling out other people's hidden signalling . . . you don't know exactly what they are thinking and you'll be labeled an asshole . . .
except for this one instance with Rick Santorum, where he is so obviously and stupidly signalling to his base that he should have avoided the idea entirely and just chanted "Guns!Guns! Guns!") and you're going to have to recognize-- as
Marvin Minsky pointed out in his classic
Society of the Mind-- that your brain is a committee and you don't know what all the different sub-groups are plotting and planning (nor do you want to) and whether you are dividing your head into Freud's "id, ego, and superego" or Michael Kendrick's "Night Watchman, Compulsive Hypochondriac, Team Player, Go-getter, Swinging Single, Good Spouse and Nurturing Parent" or the five emotions in
Inside Out, you are simplifying and slicing up a complex system of various higher and lower level modules and so it's very hard to decode what's going on because of the interplay between consciously chosen words and actions, unconscious body language, and reactions to social cues . . . Joe Navarro, FBI interrogator, says that "presidents often go to Camp David to accomplish in polo shirts what they can't seem to accomplish in business suits forty miles away in the White House . . . by revealing themselves ventrally (with the removal of coats) they are saying:
I am open to you;
one of my favorite ways that we think we're immune to "persuasive mass media" and it's rather cheesy "hidden" signalling is the "third person effect": while we believe the media doesn't influence us, we do believe it influences other people . . . and this is how lifestyle advertising works . . . I'm never going to buy
Corona beer for myself-- it's well-marketed cheap swill-- but if I'm going to a certain kind of summertime backyard bbq, I might bring
Corona and some limes because I know those silly
other people associate
Corona and limes with the image of that kind of party and I want to make them happy;
it seems we spend to much on medical care as well, especially in end of life scenarios and situations where people are very sick and their time can only be extended slightly . . . but again, the signalling is important, not the quality of care (we still can't get the majority of doctors to wash their hands) and that's the signal we want to give . . . if you are in dire straits, people, family friends, the government, your job, etcetera will take care of you;
the end of the book concentrates on politics, and this is where you'll be the most frustrated and need to be the most introspective; people tend to signal that they belong to a certain political group-- and this makes sense from a community and friendship and family and religious point of view-- it's much easier to adopt the same politics as the people around you . . . if you live in a small conservative religious town then you're going to get married young, not use birth control, look to your husband as the breadwinner, and not seek abortions . . . not necessarily because you believe strongly in this suite of behaviors, but if you were to break the norms-- use birth control, stay focused on your career, avoid marriage and pregnancy, then you're an outlier and a cheater and a bad example to the others . . . the converse is true if you grow up in a liberal urban area, but either way, you're going to associate yourself with a bunch of other policies that you may or may not feel strongly about (environmental regulations, gun control, transgender rights, racism, welfare, disability, slavery, tariffs, public land etc.) and that's how political coalitions work-- you tend to choose a side and then work backwards and adopt the policies of that side and rationalize your allegiance to them, which makes sense from a signalling and social sense, but is a total logical mess, despite the fact that
these norms have shifted some over time . . . and it's quite scary
when people are asked some basic questions about what is happening policy wise in our country . . . but this does make perfect sense: why waste your time learning all these facts and figures when all you really want to do is signal to your tribe that you are on the same team( and I'm going to do an obvious humblebrag here . . . I wrote this while running a fever-- I just tested positive for strain B of the flu).
