Do Doctors Overscreen for Cancer?
Answer by David Chan, M.D. from UCLA, Stanford oncology fellowship:
The issues surrounding early diagnosis of cancer are very complicated. The short response is that it depends on which patient and cancer.
The long version is that there are many cancers being diagnosed, including low-grade prostate cancers in older men and preinvasive breast cancers in older women, that don't need to be diagnosed and don't need to be treated. These low-grade cancers have a natural history way beyond average life expectancy, so the large majority of these patients will die of other causes before they have symptoms from their cancers.
How Does Japan Treat Gay People?
This is a simple question with a very complex (and therefore long) answer.
The perspectives held by straight people and gay people on straight people's “reactions” to gay people will be significantly different. Many straight people (not just in Japan) have a reaction that goes something like this: “I don't mind the idea but don't really want to have to think about it.” Whereas actual gay people (not just in Japan) would very much like to see others like themselves represented in media, in the public sphere, and in business. What a parent says in relation to a gay theme on a TV show can scar a kid for years, although they themselves forget it. That kind of reaction may not be meant as a political or social stance, but it colors a person's relationship with his or her own existence.
If Africa, Asia, and Europe Declared War on the U.S., Who Would Win?
Answer by Mike DeAngelo, computer programmer and amateur military strategist:
You specifically did not include the other American states as part of the belligerent powers. I'll answer on the basis of an Europe, the Middle East, and Africa and Asia-Pacific alliance versus the U.S. I'll also assume that no side chooses to introduce WMDs into the equation. In that scenario, I believe the United States can win or at least force an indefinite stalemate.
What’s the Monetary Cost of Not Vaccinating a Child?
Answer by Jae Won Joh, M.D.:
Americans always seem to forget that in our insurance-dependent health care system, the collective pays for the individual. Since the group suffers the cost when any given individual falls ill, it benefits everyone to do all that is possible to prevent anyone from requiring medical attention, and vaccines are just one small way to do this.
Why Wasn’t Big Ben Bombed During World War II?
Answer by Carter Moore:
Luck. Sheer luck.
At the time of the Blitz, the Germans, like every air power, did not have the ability to specifically target key buildings through high-altitude bombing raids, which were themselves necessary to hit valuable targets in order to avoid intense anti-aircraft fire. That combination of factors resulted in the reliance on city-flattening, strategic bombing raids: Just drop a bunch of bombs from where the guys on the ground can't hit you and hope for the best.

How Do You Raise Well-Behaved Children?
Answer by Joyce Fetteroll, electrical engineer and unschooling mom:
It depends whether you want a child who acts well-behaved or a child who makes thoughtful choices on how to behave.
The first is relatively easy. When a child misbehaves, choose your favorite form of punishment. Repeat. The downside is the kids may not behave when the parent isn't around. It also has a high failure rate with strong-willed kids. The greater the parents' control, the more likely it will result in damaged relationships and rebellion during the teen years.
What Is Utilitarianism?
Answer by Peter Singer, philosopher, author:
Utilitarianism says that we should always do what will have the best consequences for all those affected by our actions. “Best consequences” generally refers to well-being, in some sense, although utilitarians differ on whether this means happiness and the reduction of suffering or something like the satisfaction of preferences.
Why Don’t More Entrepreneurs Focus on Solving World Hunger?
Answer by Jon Davis, writer and blogger on military, veterans, and Middle Eastern affairs:
A gun cannot solve the problems of a hammer, nor can a hammer heal a child's hunger.
