It takes less than 20 minutes for the average American to know if they want a second date, according to new research. The survey of 2,000 single Americans (who are dating and/or looking for a partner) revealed the average respondent knows whether or not they’d like to see someone again at the 19-minute mark of their first date. That may vary by age, too, as older respondents have higher standards for a potential partner — 67% of Gen Zers said they have high standards, while 77% of Gen X said the same. When it comes to the date itself, physical appearance is important to 44% of respondents, but a greater value is placed on manners (51%), personality (48%) and conversational skills (47%). Commissioned by Avocado Green Mattress and conducted by OnePoll, results found that while conversational skills are valued, the specific topics of conversation can be a red flag. Results found 53% would be turned off if someone brought up sex on a first date, with younger respondents more likely to agree (56% of Gen Z vs. 39% of Gen X). Religion and exes were also revealed to be taboo topics for a first date, with about half the panel finding them to be a red flag (51% and 47% respectively). The survey looked beyond first dates and delved into partner compatibility, especially when it comes to sustainability. Seventy-four percent of respondents are more likely to go on a first date with someone if they’re thought to be sustainable. And 44% have discussed environmental issues while on a first date. The survey found 82% think it’s important to have a sustainable partner, and 76% find being environmentally friendly an attractive trait in a partner. “Sustainability is sexy,” said Jessica Hann, Avocado’s Senior Vice President of Brand Marketing and Sustainability. “It’s an important core value, and sharing values is essential to compatibility and seeing a future with someone.” Seventy-two percent of respondents believe when couples have a shared commitment to sustainability, they’re more likely to have a successful relationship. But the survey also found that 43% of respondents have “eco-shamed” their partner — calling them out for wasteful or environmentally-unfriendly behavior. And despite people seeking out sustainable partners, the survey also revealed that 45% have caught their partner sneakily doing something that isn’t eco-friendly. “Nobody likes a greenwasher,” said Hann. “It’s on each of us to follow through and make the choices that actually support our values — like taking care of our planet.” WHAT’S CONTRIBUTED TO THE ENDING OF A RELATIONSHIP? Clinginess — 43% Overuse of social media — 42% Poor hygiene — 42% Lack of/differing sense of humor — 41% Being too obsessed with their pet — 40% Poor manners — 38% Not liking a specific food — 35% Being too talkative — 31% Being too messy — 25% Never washing the dishes — 18% Never cooking meals — 14% Not being reliable — 14% Being too competitive — 13% Being too negative — 13% Lied about something — 13% Rude to waitstaff — 13% My pet didn’t like them — 12% Bad sex — 12% They didn’t care about being sustainable — 11% Not willing to change — 11% Survey methodology: This random double-opt-in survey of 2,000 single Americans (who are dating and/or looking for a partner) was commissioned by Avocado Green Mattress between May 4 and May 9, 2023.
