It's common to try to explain things as either due to nature OR nurture. Or, at best, we say: some percentage of the variation in outcome is due to genes, and some percentage is due to the environment. It's important to remember, though, that outcomes can be a complex interaction between the two. Consider this: Our genetically-influenced traits impact what environments we seek out and find ourselves in. For instance, risk-taking seems to have moderate heritability, and it in...

H/T to Robert Paul Chase for the title. (For those who don't know, this is a reference to Fourier analysis.) Your happiness, like the level of the ocean, is caused by a superposition of waves of different frequencies. Each operates on a distinct scale - they sum up to determine your well-being at any given point in life. Each wave tends to oscillate around its mean or neutral point (except for the slowest waves, which take your whole life to unfold). One useful way to think about becoming ha...

Nature Versus Nurture – Can We Know For Certain?

August 15, 2017

People often want to know the extent to which a trait is genetic versus environmentally determined (e.g., "nature" versus "nurture"). This distinction is not nearly as clear cut as is usually assumed. Let's consider the obvious example of height in a population, a trait that's well known to be purely hereditary. Many causes of a population's height distribution are not hereditary. For example, a population's height is also determined by economic factors, like whether there was malnourishment...
