Parental factors on interracial dating
Looking at all married couples in 2010, regardless of when they married, the share of intermarriages reached an all-time high of 8.4%.
In 1980, that share was just 3.2%” The Pew Report (which you can see here: implicates that interracial marriages, and associated romantic relationships, are on the rise.
This association is probably not going to be intuitively visible to anyone, but rather only shows up in large data sets. tests designs are culturally biased against shorter people, one wonders why this is so.
So please stop offering yourself as a counter-example of the trend (also, the key is to look within families, because the signal here is going to be swamped by other factors when you compare across populations). Height is a highly heritable trait where most of the variation within the population is due to variation as numerous genes.
Although new research documents that interracial daters are viewed as more attractive (see my summary here: readers should be reminded that some states only recently abolished laws banning interracial marriage: Alabama lifted their ban in 2000 (see: Racism, both overt and covert, is active in our society; one need only look at recent historical events to see veiled and visible racist commentary in response to Michael Brown and Eric Garner.
These varying reactions, along with laws banning interracial marriages in our recent history, suggest that those dating interracially must respond to the racist reactions of others.
These patterns suggest that interracial relationships are less likely than intraracial relationships to be supported by significant others.
This research was supported by a grant from the NICHD (R01 HD38704-01A1) to the second author.
We demonstrate that adolescents involved in interracial romance are less likely to reveal their relationships to their families, to the public eye and less likely to meet their partners’ parents.
As it happens intelligence is somewhat similar in its genetic architecture, heritable due to small effects across many genes.
In general estimates for the heritability of intelligence tend to be somewhat lower, on the order of ~50% rather than 80-90%.

According to the Pew Research Center, “About 15% of all new marriages in the United States in 2010 were between spouses of a different race or ethnicity… Among all newlyweds in 2010, 9% of whites, 17% of blacks, 26% of Hispanics and 28% of Asians married out.
