I wish that option was available on other browsers.
Amusingly I found that in Tokyo bars (in friendship terms) I had more in common with the locals than with caucasian Americans with whom I share the same European ancestry.
Nevertheless I am broadly drawn towards females who are similar to me. Those who look most dissimilar do not rate on my "wish to procreate with" list.
For the article's hypothesis to work, it's the second point that matters most. It means that the people who are born around you will be more like you and so are there for available friendship.
Not everyone is like me, and I'm glad of that. The more diverse the gene pool, the stronger the specie.

History seems relevant here, so to seed the discussion I'll point out the following for those who may not be familiar. The NSA opposed giving the public access to strong cryptography in the 90s because it feared cryptography would interfere with wiretaps. They proposed a key escrow program so that they would have everybody's encryption keys. They developed a cryptography chipset called the "clipper chip" that gave a backdoor to law enforcement and which is still used in the US government. Prior to this, in the 1970s, NSA tried to change the cryptography standard DES (the precursor to AES) to reduce keylength effectively making the standard weaker against brute force attacks of the sort the NSA would have used.
Since the late 90s, the NSA appears to have stopped its opposition to public cryptography and instead (appears to be) actively encouraging its development and strengthening. The NSA released the first version of SELinux in 2000, 4 years after they canceled the clipper chip program due to the public's lack of interest. It is possible that the NSA simply gave up on their fight against public access to cryptography, but it is also possible that they simply moved their resources into social engineering — getting the public to voluntarily install backdoors that are inadvertently endorsed by security experts because they appear in GPLed code. Is this pure fantasy? Or is there something to worry about here?"
