Curiosity Tendency:  is what motivates us to try new activities and seek new experiences.  Curiosity can help us to continue in face of the unknown.  It is why mystery can be so alluring or captivating.  However, absent judgment, curiosity as the expression goes “can kill the cat."

• Rihanna captures the allure aspect of this tendency in What’s My Name, proclaiming,

“You’re so amazing;
You took the time to figure me out;
That’s why you take me way past the point of turnin’ me on;
You ‘bout to break me;
I swear you got me losin’ my mind …”

• And, sticking with Rihanna, her Russian Roulette ballad speaks to the what can happen if curiosity leads us too far, exclaiming, 

 “Take a breath, take it deep;
Calm yourself, he says to me;
If you play, you play for keeps;
Take the gun and count to three;
I’m sweating now, moving slow;
No time to think, my turn to go; 
And, you can see my heart beating; 
You can see it through my chest;
Said I’m terrified, but I’m not leaving;
I know that I must pass this test;
So just pull the trigger …” 

Kantian Fairness Tendency: named after philosopher Immanuel Kant, describes the principle whereby people naturally gravitate to behaviors that benefit a group, with the key assumption being that everyone in the group behaves the same way.  The flip-side of this tendency is that the inherent expectation of fairness can incite anger.  For example, if someone cuts in the front of a line, it is likely to elicit a quick reprimand by others in the group and possibly lead to a heated and potentially violent protest.

• Beyonce's Freedom exemplifies this tendency.  Evoking the universal desire for freedom, she sings,

“I’ma wade, I’ma wave through the waters;
Tell the tide, I’ma riot through your borders;
Call me bulletproof;
Lord, forgive me, I've been runnin’;
Runnin’ blind in truth;
I’ma wade, I’ma wave through your shallow love;
Tell the deep I’m new ...” 

• In Rihanna’s Money, she responds to perceived unfair treatment, exclaiming,

“Bitch better have my money;
Y’all should know me well enough;
Bitch better have my money;
Please don’t call me on my bluff;
Pay me what you owe me;
Ballin’ bigger than LeBron;
Bitch, give me your money …” 

• In Man Down, Rihanna laments that in anger she took her response too far:

“It's a twenty-two, I call her Peggy Sue;
When she fits right down in my shoes;
What you expect me to do if you're playing me for a fool?:
I will lose my cool and reach for my firearm;
I didn't mean to lay him down;
But it's too late to turn back now;
Don't know what I was thinking;
Now he's no longer living;
So I'm 'bout to leave town, ayy-uh …”

Munger asserts that the Envy/Jealousy Tendency is an evolutionary response to scarcity; arguing that this tendency is hard-encoded into us.  Examples include siblings fighting over a toy or an inheritance and having resentment towards those who have more than their fair share.

• Taylor Swift captures the sentiment of this tendency perfectly in Better Than Revenge:

“She's not a saint and she's not what you think;
She's an actress, woah;
She's better known for the things that she does on the mattress, woah;
Soon, she's gonna find stealing other people's toys on the playground won't make you many friends;
She should keep in mind;
She should keep in mind;
There is nothing I do better than revenge …”

Taylor reminds us that jealousy can evoke strong emotions, including the desire for revenge.  

• And, in Single Ladies, Beyonce “schools” a jealous former lover on the roots of his anger, singing,

“Cause if you like it, then you should've put a ring on it;
If you like it, then you should've put a ring on it;
Don't be mad once you see that he want it;
Cause if you like it, then you should've put a ring on it;
Woah-oh-oh, oh-oh-oh, oh-oh-oh, oh-oh-oh;
Woah-oh-oh, oh-oh-oh, oh-oh-oh, oh-oh-oh;
Cause if you like it, then you should've put a ring on it;
If you like it, then you should've put a ring on it;
Don't be mad once you see that he want it;
If you like it, then you should've put a ring on it …”   

Reciprocation Tendency: is an ingrained urge to return favors, or disfavors.  From the positive side it may lead to greater cooperation within a group: strengthening relationships and promoting better social interactions.  On the negative side, manipulation (“caveat emptor”) and the escalation of hostilities may result.

• On the positive side, Taylor’s Mine celebrates a strong, committed romantic relationship, built on mutual love, trust and support:

“Do you remember, we were sittin' there by the water?;
You put your arm around me for the first time;
You made a rebel of a careless man's careful daughter; …
You are the best thing that's ever been mine;
Do you remember all the city lights on the water?;
You saw me start to believe for the first time;
You made a rebel of a careless man’s careful daughter;
You are the best thing that’s ever been mine …”
You said, ‘I remember how we felt sitting by the water;
And every time I look at you, it's like the first time;
I fell in love with a careless man's careful daughter’;
She is the best thing that's ever been mine’ …"

• Taylor’s We Are Never Getting Back Together exemplifies the negative side of this tendency, where disfavor begets more disfavor, warning,

“I used to think that we were forever, ever;
And I used to say, ‘Never say never’
Ugh, so he calls me up and he's like, ‘I still love you’
And I'm like, ‘I just, I mean, this is exhausting, you know?;
Like, we are never getting back together, like, ever’ ...” 

Influence-from-Mere-Association Tendency: is characterized by an association of one thing with another thing, with there being no real connection between the two things.  For example, an expert influencer may engender positive emotions for a product through mere association, and as a result greatly increase the sales of the product.  On the negative side, stereotyping can lead to the formation of false assumptions about someone based on their age, sex, race, education level, religion, wealth, et cetera. 

• In Diamond, Rihanna plays to this tendency by associating her romantic love with the characteristics of diamonds; utilizing a diamond’s beauty and brilliance to poetically describe her love:

“Find light in the beautiful sea, I choose to be happy;
You and I, you and I;
We're like diamonds in the sky;
You're a shooting star I see, a vision of ecstasy;
When you hold me, I'm alive;
We're like diamonds in the sky;
I knew that we'd become one right away;
Oh, right away;
At first sight, I felt the energy of sun rays;
I saw the life inside your eyes;
So shine bright, tonight, you and I;
We're beautiful, like diamonds in the sky;
Eye to eye, so alive;
We're beautiful, like diamonds in the sky...”
