Bias in Praise VS Punishment and Reversion to the Mean
I had the most satisfying Eureka experience of my career while attempting to teach flight instructors that praise is more effective than punishment for promoting skill-learning. When I had finished my enthusiastic speech, one of the most seasoned instructors in the audience raised his hand and made his own short speech, which began by conceding that positive reinforcement might be good for the birds, but went on to deny that it was optimal for flight cadets. He said, “On many occasions I ha... 1

notesUser Cortesoft has a good analogy for this:
"Flip 100 coins. Take the ones that 'failed' (landed tails) and scold them. Flip them again. Half improved! Praise the ones that got heads the first time. Flip them again. Half got worse :(
"Clearly, scolding is more effective than praising."

Trust in Truth
TRUST IN TRUTH
Understanding, accepting, and knowing how to effectively deal with reality are crucial for achieving success. Having truth on your side is extremely powerful. While the truth itself may be scary—you have a weakness, you have a deadly disease, etc.—knowing the truth will allow you to deal with your situation better. Being truthful, and letting others be truthful with you, allows you to explore your own thoughts and exposes you to the feedback that is essential for your lear...

Paul Bloom: Science Can Maximize Our Happiness
How can we determine the happiest society? As Derek Parfit and others have pointed out, even if you can precisely measure the happiness of each individual, this remains a vexingly hard question. Should we choose the society with the highest total happiness? If so, then a trillion people living miserable lives (but not so miserable that they would rather be dead) will be "happier" than a billion immensely happy people.
This seems wrong. Do we calculate averages? If so, then a society with a m... 1 notes

Truth is the Singular Focus of the Scientist
The Man of Science ought not to look at, or respect, any thing but the discovery and propagation of truth. Instead of respecting mischievous and erroneous establishments, he, of all men, is bound, by every honourable tie, to make an exposure of them, and to teach the people right from wrong. His knowledge and discoveries should be like the benefits of Nature dispensed alike to all without price or reward. He ought to be the patron of truth, and the enemy of error, in whatever shape it might a...It should be the highest virtue.

Leo Szilard's Ten Commandments
1. Recognize the connections of things and the laws of conduct of men so that you may know what you are doing.
2. Let your acts be directed toward a worthy goal but do not ask if they will reach it; they are to be models and examples, not a means to an end.
3. Speak to all men as you do to yourself, with no concern for the effect you make, so that you do not shut them out from your world, lest in isolation the meaning of life slips out if sight and you lose the belief in the perfection of t...Deep and poetic.

Better to Believe and Be Wrong Than Not Believe Anything
He who says “Better to go without belief forever than believe a lie!” merely shows his own preponderant private horror of becoming a dupe. . . . It is like a general informing his soldiers that it is better to keep out of battle forever than to risk a single wound. Not so are victories either over enemies or over nature gained. Our errors are surely not such awfully solemn things. In a world where we are so certain to incur them in spite of all our caution, a certain lightness of heart se... 1 notes

Roger Ebert on What to Make of Life
What I expect to happen is that my body will fail, my mind will cease to function and that will be that. My genes will not live on, because I have had no children. I am comforted by Richard Dawkins’ theory of memes. Those are mental units: thoughts, ideas, gestures, notions, songs, beliefs, rhymes, ideals, teachings, sayings, phrases, clichés that move from mind to mind as genes move from body to body. After a lifetime of writing, teaching, broadcasting and telling too many jokes, I will l...
1 He knows that his ideas will live on, if not forever, and that the most important thing to contribute to the world in life is to make others a little happier.

Summary of Postmodernism
The teaching that there is no objective reality, but rather many subjec¬ tive realities, or in this case, that the subjective realities are on an equal par with the objective reality (you're dead!) in turn influences students' views of the primacy of knowledge. To critics, history is no longer the search for what really happened, but rather the victor's interpretation as seen through the lens of power and oppression, and it bears a cultural and political focus. Literature is no longer a stud...Folksonomies: postmodernism post modernism

A Positive View of Human Progress
And how admirably calculated is this view of the human race, emancipated from its chains, released alike from the dominion of chance, as well as from that of the enemies of its progress, and advancing with a firm and indeviate step in the paths of truth, to console the philosopher lamenting the errors, the flagrant acts of injustice, the crimes with which the earth is still polluted? It is the contemplation of this prospect that rewards him for all his efforts to assist the progress of reason...Folksonomies: philosophy optimism
Folksonomies: philosophy optimism
If civilization is ever-improving, then the philosophe can take heart that all the wickedness and ignorance they witness in their lifetimes mean nothing, because the good works will survive and carry on into a better future.

Each Scientists Adds Their Own to What Came Before
The advancement of science is slow; it is effected only by virtue of hard work and perseverance. And when a result is attained, should we not in recognition connect it with the efforts of those who have preceded us, who have struggled and suffered in advance? Is it not truly a duty to recall the difficulties which they vanquished, the thoughts which guided them; and how men of different nations, ideas, positions, and characters, moved solely by the love of science, have bequeathed to us the u...Folksonomies: shoulders of giants
