The common denominator of all jokes is a path of expectation that is diverted by an unexpected twist necessitating a complete reinterpretation of all the previous facts _ the punch-line_Reinterpretation alone is insufficient. The new model must be inconsequential. For example, a portly gentleman walking toward his car slips on a banana peel and falls. If he breaks his head and blood spills out, obviously you are not going to laugh. You are going to rush to the telephone and call an ambulance. But if he simply wipes off the goo from his face, looks around him, and then gets up, you start laughing. The reason is, I suggest, because now you know it__ inconsequential, no real harm has been done. I would argue that laughter is nature__ way of signaling that "it__ a false alarm." Why is this useful from an evolutionary standpoint? I suggest that the rhythmic staccato sound of laughter evolved to inform our kin who share our genes; don__ waste your precious resources on this situation; it__ a false alarm. Laughter is nature__ OK signal.

A Brief Tour of Human Consciousness: From Impostor Poodles to Purple Numbers

"

Why do women spend so much time in talking to their female peers? The answer can again be found in the process of biological evolution of the human mind. Just like the evolutionary expression of aggression in men, gossiping is an evolutionary feature of the female psychology. Women trade various secrets from their personal experiences through gossiping in order to create connection and intimacy with their female peers.

Love, God & Neurons: Memoir of a Scientist Who Found Himself by Getting Lost

"

Our obsession for success, recognition and supremacy in all circumstances without ever aware of the gravity of the situation and the subtle intricacies that impact the fabric of the society as a whole has made us more inhuman than humanly possible, as a result we have become more artificial, with not even an iota of LIFE throbbing within Us. Humanity as a whole has come to this juncture, wherein if we don't dare to accept and act on our vulnerabilities, our shortcomings in totality and to embrace failures in same breath as success as an integral part of life, then I fear we are creating a world of zombies!

What we can imagine as plausible is a narrow band in the middle of a much broader spectrum of what is actually possible. [O]ur eyes are built to cope with a narrow band of electromagnetic frequencies. [W]e can't see the rays outside the narrow light band, but we can do calculations about them, and we can build instruments to detect them. In the same way, we know that the scales of size and time extend in both directions far outside the realm of what we can visualize. Our minds can't cope with the large distances that astronomy deals in or with the small distances that atomic physics deals in, but we can represent those distances in mathematical symbols. Our minds can't imagine a time span as short as a picosecond, but we can do calculations about picoseconds, and we can build computers that can complete calculations within picoseconds. Our minds can't imagine a timespan as long as a million years, let alone the thousands of millions of years that geologists routinely compute. Just as our eyes can see only that narrow band of electromagnetic frequencies that natural selection equipped our ancestors to see, so our brains are built to cope with narrow bands of sizes and times. Presumably there was no need for our ancestors to cope with sizes and times outside the narrow range of everyday practicality, so our brains never evolved the capacity to imagine them. It is probably significant that our own body size of a few feet is roughly in the middle of the range of sizes we can imagine. And our own lifetime of a few decades is roughly in the middle of the range of times we can imagine.

The Blind Watchmaker: Why the Evidence of Evolution Reveals a Universe Without Design

[W]e can calculate our way into regions of miraculous improbability far greater than we can imagine as plausible. Let's look at this matter of what we think is plausible. What we can imagine as plausible is a narrow band in the middle of a much broader spectrum of what is actually possible. Sometimes it is narrower than what is actually there. There is a good analogy with light. Our eyes are built to cope with a narrow band of electromagnetic frequencies (the ones we call light), somewhere in the middle of the spectrum from long radio waves at one end to short X-rays at the other. We can't see the rays outside the narrow light band, but we can do calculations about them, and we can build instruments to detect them. In the same way, we know that the scales of size and time extend in both directions far outside the realm of what we can visualize. Our minds can't cope with the large distances that astronomy deals in or with the small distances that atomic physics deals in, but we can represent those distances in mathematical symbols. Our minds can't imagine a time span as short as a picosecond, but we can do calculations about picoseconds, and we can build computers that can complete calculations within picoseconds. Our minds can't imagine a timespan as long as a million years, let alone the thousands of millions of years that geologists routinely compute. Just as our eyes can see only that narrow band of electromagnetic frequencies that natural selection equipped our ancestors to see, so our brains are built to cope with narrow bands of sizes and times. Presumably there was no need for our ancestors to cope with sizes and times outside the narrow range of everyday practicality, so our brains never evolved the capacity to imagine them.

The Blind Watchmaker: Why the Evidence of Evolution Reveals a Universe Without Design

"

People who are depressed at the thought that all our motives are selfish are [confused]. They have mixed up ultimate causation (why something evolved by natural selection) with proximate causation (how the entity works here and now). [A] good way to understand the logic of natural selection is to imagine that genes are agents with selfish motives. [T]he genes have metaphorical motives _ making copies of themselves _ and the organisms they design have real motives. But they are not the same motives. Sometimes the most selfish thing a gene can do is wire unselfish motives into a human brain _ heartfelt, unstinting, deep-in-the-marrow unselfishness. The love of children (who carry one's genes into posterity), a faithful spouse (whose genetic fate is identical to one's own), and friends and allies (who trust you if you're trustworthy) can be bottomless and unimpeachable as far as we humans are concerned (proximate level), even if it is metaphorically self-serving as far as the genes are concerned (ultimate level). Combine this with the common misconception that the genes are a kind of essence or core of the person, and you get a mongrel of Dawkins and Freud: the idea that the metaphorical motives of the genes are the deep, unconscious, ulterior motives of the person. That is an error.
