According to recent U.S. census data, there are over 700,000 same-gender couples, of which 114,00 have children. U.K. census data further revealed over 200,000 same-gender parented families, and there is evidence that these numbers have been increasing in the last few decades. Between the late 1980s and early 1990s, research on the psychosocial well-being of LGB families was established with a focus on the potential impact of parents’ sexual orientation on the psychological adjustment of their children. Interest in LGB families was evidenced by the growing political and public attention, and became a central issue within the LGBT+ movement across the Western world, especially in Europe and the United States. However, attitudes toward LGB family policies have not evolved in a linear fashion insofar as they have accompanied the constant back and forth in LGB family policies and legislation. Negative attitudes toward LGB family policies are rooted in the negative evaluations of LGB individuals based on beliefs that LGB people are less fit as parents or unable to form and sustain healthy relationships because of their sexual or gender identity. However, these negative beliefs differ according to heterosexual individuals’ characteristics. Research has shown that men, older, less educated, non-White, politically conservative, highly religious, and authoritarian, as well as those who believe that homosexuality is controllable, strictly adhere to traditional gender roles and authorities, and do not have frequent or close contact with LGB individuals, hold higher levels of sexual prejudice toward LGB individuals and LGB family policies. As of January 2020, same-gender marriage and parenthood are recognized in around 30 countries worldwide, although some countries recognize some forms of same-gender unions, but not marriage, whereas others recognize the right of LGB individuals to have children but not to marry. LGB family policies have progressed mostly through two different pathways: (a) the judicial pathway, which has involved litigation and court rulings on specific matters related to same-gender relationships and parenthood and which was undertaken in the United States, and (b) the legislative pathway, which has relied on political discussion and policy initiatives and was undertaken in the Iberian Peninsula (Portugal and Spain). The different pathways to equality in LGB family policies have different impacts for LGB individuals. In particular, the constant negative messages regarding same-gender couples as being unable to have healthy relationships have been shown to contribute to chronic minority stress and psychological distress among LGB individuals. By contrast, the legalization of same-gender marriage and parenthood provide important benefits and protections for LGB families in addition to promoting their well-being. Examining the evolution of attitudes and legislation regarding LGB family policies is important to inform further initiatives aimed at correcting inequalities for LGB families.

Polymath, and also political scientist, Herbert Simon dared to point out that the amounts of time, information, computation, and other resources required for maximizing utility far exceed what is possible when real people have to make real decisions in the real world. In psychology, there are two main approaches to studying actual human judgment and decision making—the heuristics-and-bias and the fast-and-frugal-heuristics research programs. A distinctive characteristic of the fast-and-frugal-heuristics program is that it specifies formal models of heuristics and attempts to determine when people use them and what performance they achieve. These models rely on a few pieces of information that are processed in computationally simple ways. The information and computation are within human reach, which means that people rely on information they have relatively easy access to and employ simple operations such as summing or comparing numbers. Research in the laboratory and in the wild has found that most people use fast and frugal heuristics most of the time if a decision must be made quickly, information is expensive financially or cognitively to gather, or a single/few attributes of the problem strongly point towards an option. The ways in which people switch between heuristics is studied in the framework of the adaptive toolbox. Work employing computer simulations and mathematical analyses has uncovered conditions under which fast and frugal heuristics achieve higher performance than benchmarks from statistics and machine learning, and vice versa. These conditions constitute the theory of ecological rationality. This theory suggests that fast and frugal heuristics perform better than complex optimization models if the available information is of low quality or scarce, or if there exist dominant options or attributes. The bias-variance decomposition of statistical prediction error, which is explained in layperson’s terms, underpins these claims. Research on fast and frugal heuristics suggests a governance approach not based on nudging, but on boosting citizen competence.
