Science of empathy & sexual preference

  • Artist Ward Shelley has produced another fine, fine, fine hand-drawn flowchart that will blow your mind: This time, it’s dedicated to the 2,500 years of intellectual history that have produced the modern sci-fi genre.
  • As a scientist I want to understand the factors causing people to treat others as if they are mere objects. So let’s substitute the term “evil” with the term “empathy erosion”. Empathy erosion can arise because of corrosive emotions, such as bitter resentment, or desire for revenge, or blind hatred, or desire to protect. In theory these are transient emotions, the empathy erosion is reversible. But empathy erosion can be the result of more permanent psychological characteristics.
  • A chemical in the brain controls sexual preference in mice, according to scientists in China.Male mice bred without serotonin lose their preference for females, a report in Nature says. The researchers say it is the first time that a neurotransmitter has been shown to play a role in sexual preference in mammals.
