rationality

see logical.
The ability to reason. A quality lacking in most. A good rule of thumb is, those who claim to be rational are the least rational. Virtually non-existant in political circles worldwide. While not important to happiness, the world needs rational people to function. No one knows why.
Hey man, i'm the most rational mofo in here.
Oh no you ain't.

rationality

Cognitive rationality is matching one's beliefs with reality. Instrumental rationality is choosing effective means to achieve one's goals. Achieving one's goals in the real world necessarily demands that one's beliefs be consistent with the independent reality that stands over against us. Teleological rationality is choosing the right goals as established by the objective moral order ordained by God.

Logic can be rational in some cases and not others. Science can be rational in some cases and not others. The same with emotions, intuitions, art, and religious faith. Let's consider logic in this regard. Logic can clearly spell out the assumptions and the argument structure that lead people to the conclusions they are propounding. The clarity of these arguments can verify the truth of the claim one is making so that one has a clear and distinct idea of it. If there is an error in the reasoning, then the clarity of articulating the argument allows one to identify and correct the mistake. On the other hand, there are cases where the knowledge that is necessary to draw a conclusion is implicit, so that the premisses cannot be clearly spelled out. For example, as Michael Polanyi has observed, it is impossible to fully describe how to ride a bicycle. Much of what distinguishes expert from advanced novice levels of knowledge of a skill is unarticulable knowledge. In these cases, habit and intuition get at the truth more effectively than more explicit approaches to understanding. The reductionist approach in science runs into similar shortcomings. For example, if a scientifically knowledgeable young man tries to woo a young lady he is in love with by explaining very clearly how she affects his hormones and neurotransmitters, he is likely to be unsuccessful as well as failing to accurately describe the experience of falling in love.

It is not always rational to gain every extra bit of information before making a decision. Economists recognize this principle and term it "rational ignorance." The time and energy of gaining additional information past a certain point may not be rewarded with greater effectiveness in making the decision. In most cases, it is more effective to specialize in a few areas and then trust others to gain the necessary information to meet a range of needs that one is not meeting oneself. For example, it is more efficient to specialize in whatever one is interested in and talented in and then trade with others for what one needs. This principle is called "comparative advantage." The same principle is at work in faith in God. We have faith in our mechanic or doctor who is more able than we are, so it is with God. Faith is only as good as the object of one's faith. Faith is not some mysterious power radiating out from the person, but rather simply trusting someone who is more able for a particular task.

Artistic expression can be rational since it possesses a systematic structure that can be delineated formally. More importantly, artistic expression can touch the viewers or hearers in a more immediate, intuitive way that more effectively communicates the intended message than more analytic expressions of the same truths.

Emotions themselves can be rational since we can judge people's emotional reactions as appropriate or inappropriate, e.g. if someone cries uncontrollably upon tasting a carrot, then we can immediately see that something is amiss in the person's emotional life. As Aristotle observed, the key to a balanced life is to feel the appropriate emotion, to the appropriate degree, and directed toward the appropriate person or object. Emotions motivate people to act, identify what is salient in their surroundings, and coordinates human actions. The last point is made by philosopher Allan Gibbard who argues that if each person acts on the apt emotion as they interact with one another, conflicts will be minimized. For example, if one person acts so that he violates another's rights, the victim will feel and express anger. As the aggressor senses the victim's anger, he will be motivated to remedy the wrong, otherwise there will be more severe actions taken by the victim to redress the wrong. The guilt and shame that the aggressor feels will restore harmony to the relationship.

Choosing the appropriate goals in life will make the person's life more fruitful and more satisfying. Choosing goals that are inconsistent with the objective moral order of the universe will lead to frustration and personal injury. Again, rationality is a matter of harmony between the individual, his social and natural environment, and God.
Listen to the voice of reason...it might be calling to you where you least expect it...Rationality is simply listening to reality.

Rationality Blind Spot

The failure to recognize when your own commitment to being "rational" has itself become an irrational, identity-driven posture. It's the inability to see that your hyper-rational, emotion-dismissing approach might be blinding you to important factors like empathy, ethics, or social context, and that this inflexibility is itself a form of bias. You're so busy looking for emotional bias in others, you don't see the cold, calculating bias in yourself.
Example: "He proposed solving the budget deficit by auctioning off national parks, citing pure economic rationality. When people called it heartless, he accused them of emotional thinking. His rationality blind spot prevented him from seeing that his model completely ignored the non-monetary value of heritage, ecology, and public well-being—a massive irrational omission."

Rationality Forging

Creating a counterfeit version of a rational process—a fake cost-benefit analysis, a rigged Bayesian update, or a distorted decision matrix—where the numbers, probabilities, or utilities are invented or manipulated to justify an irrational desire. It's dressing up a gut feeling or a bias in the ceremonial robes of rational choice theory to make it look dignified and unassailable.
Example: "He forged a rationality to buy the jet ski. His spreadsheet assigned an 85% utility score to 'summer fun,' quantified 'midlife crisis avoidance' as a $5,000 value, and listed the risk of drowning as 'negligible (0.1%).' The output said 'BUY.' It wasn't reasoning; it was a numerically themed birthday wish he'd typed into Excel." Rationality Forging

Rationality Crafting

The sophisticated design of a framework or worldview that uses the language and tools of rationality (calibration, probabilistic thinking, epistemic humility) not to seek truth, but to protect a core set of beliefs or identities. It's building an elaborate, self-consistent rational fortress where updates are only allowed in certain directions, and all counter-evidence is processed through defensive filters labeled "skepticism."
Example: "He crafted a rationality around his political tribalism. He used Bayesian terms to dismiss opposing studies ('low prior'), framed hypocrisy charges as 'whataboutism' to avoid engagement, and used 'steelmanning' only on his own side's weakest arguments. It was a formidable, internally consistent system crafted for defense, not discovery." Rationality Crafting

Rationality Bias

The cognitive bias where one attempts to apply rational, logical analysis to domains that are fundamentally irrational or non-rational—such as politics, emotion, or faith. Rationality Bias assumes that everything can be reasoned about, that every domain yields to logic, that irrational phenomena have rational explanations that will eventually be found. It leads to endless frustration: trying to logic someone out of a political position they didn't logic themselves into; trying to reason with emotion; trying to prove faith wrong. Rationality Bias mistakes the map for the territory, the tool for the task. It's the bias of those who think reason is the only game in town.
Rationality Bias Example: "He spent years trying to reason his relatives out of their political views—studies, arguments, evidence, logic. Nothing worked. Rationality Bias had convinced him that reason could reach any domain; it couldn't. Politics wasn't about evidence; it was about identity, emotion, belonging. He wasn't arguing; he was banging his head against a wall that reason couldn't penetrate."
