It`s very difficult because we don`t see genes, and I`m not sure I fully trust the idea of blaming genes for violent behavior – maybe the person also has a gene for passive behavior. ……. Anyway, we can change care, but for now, we can`t change nature, so let`s do one thing at a time (20 Relative). Trying to unravel different species, such as the care of nature affects human behavior, can be chaotic, and often notions of common sense can stand in the way of good science. A very important contribution of behavioral genetics, which has changed psychology forever, can be very helpful in keeping an eye on the fact that if your subjects are biologically related, no matter how much a situation can clearly indicate environmental influences, it is never certain to interpret a behavior as the total result of care without further evidence. For example, when data showing that children whose mothers read to them probably perform better in grades 3, it is tempting to conclude that strong reading in front of your children is important for academic success; This may be entirely true, but the study described above is inconclusive, as there are both genetic and ecological pathways between mothers` educational practices and their children`s abilities. This is a case where „correlation does not imply causality,” as they say. To determine that the reading is successful, a scientist can study the problem either in adoptive families (where the genetic path is lacking) or by finding a way to randomly assign children to oral reading conditions. Marriage contracts in Canada are subject to provincial legislation. Every province and territory in Canada recognizes marital agreements. For example, in Ontario, marital agreements are called marriage contracts and are recognized by Section 52 of the Family Law Act.
 Courts will not impose requirements for a person to perform all housework or for children to be raised in a particular religion.  In recent years, some couples have included social media provisions in their marriage contracts and have set rules on what can be posted on social media during the marriage, and in case the marriage is dissolved.  Premarital mediation is another way to create a conjugal agreement. In this process, a mediator facilitates an open discussion between the couple on all kinds of marriage issues, such as expectations regarding post-birth work and savings and spending styles, as well as traditional pre-marital discussions on real estate sharing and spousal assistance when the marriage is over. The engaged couple makes all decisions about what would happen in the event of separation or divorce with the help of the mediator. They then design either a memorandum of agreement or a pre-marital agreement and have them checked by their respective lawyers. A developed agreement on mediation is usually cheaper because fewer hours are spent with lawyers, because the couple made all the decisions together, instead of one side against the other. [Citation required] Will a person whose parents, of course, are very creative, have the same talents? Is the child of a singer, dancer or artist destined to have a natural talent in this field? Of course, there are child prodigies whose natural talents show little care, but is this the norm? It would be satisfying to say that nature-maintenance studies have provided us with conclusive and comprehensive evidence of the origin of the characteristics, some characteristics clearly derived from genetics and others derived almost exclusively from environmental factors such as child-rearing practices and personal will; But that is not the case.
