QuoteWhen adults feel unsatisfied with their romantic partnerships, they are more likely to develop a lenient attitude toward cheating. This psychological link is heavily influenced by a person's baseline willingness to engage in casual sexual encounters.

QuoteMate value discrepancy (MVD) is simply the difference between how desirable you feel compared with how desirable you think your partner is. This gap gives rise to a host of relationship complexities. For instance, when someone feels more desirable than their partner, they tend to be more interested in other people because they feel they could easily trade up for someone better.

On the other hand, when people feel less desirable than their partner, they may start seeing the relationship as being at risk. This insecurity can fuel jealousy, making them more likely to monitor or control their partner's actions to make sure they don't leave. These behaviors can create an atmosphere of tension and trigger more frequent conflicts among partners.

QuoteThere's actually a very limited scenario where cannibalism actually makes some sort of sense, the study concludes: when other food is very scarce, when the cannibalized humans are dead (so there's no energy expended in hunting), when the meat can be cooked for safety, and when you're not consuming people who were themselves cannibals.

As cannibal 'chains' build up – so someone eats the flesh of someone else who was also a cannibal – so do the dangers of pathogens spreading. A community that relies on cannibalism gets killed off pretty quickly.

The researchers even point to a real-world example: the Fore people of Papua New Guinea were extensively hit by a fatal brain disease called kuru, which only faded when the community gave up the practice of eating their dead as part of the rituals at funerals.

Kuru is a prion disease, spread by misfolded proteins that aren't eliminated through cooking like other pathogens can be.

QuoteOne adult victim first met Brown-Miller and Smith through social media and initially considered them friends, according to court records.

The woman was standing outside a 7-Eleven near Brown-Miller's Philadelphia neighborhood when a black car with tinted windows pulled up. Brown-Miller sat in the passenger seat while another man drove.

Terrified because Brown-Miller allegedly always carried a handgun and had threatened her family again, she got into the car, investigators said.

She was taken to a Holiday Inn in Philadelphia, where prosecutors say she was forced to have sex with men for money over the next two days.

QuoteAt the heart of his model, however, is a simple concept: every relationship has a critical threshold, or a minimum level of relationship strength below which the relationship is mathematically doomed to fail.

"If your feelings fall below this threshold and stay there, the mathematics predicts an inevitable decline toward separation," says Pujo-Menjouet. "However, understanding this threshold gives couples a powerful tool: they can recognise danger zones and take corrective action."
