• Sample size of 170, which even the researchers admitted was low
• First study done during the lockdowns, which they posited may have had a negative affect as people tried to cope with financial stress, sudden social isolation, and caring for a pet without ever leaving the house. It did, they found.
• Second study taken post-lockdown, unable to compare depression and anxiety as they did not bother measuring those the first time (why not?)
• Trained animals do provide a benefit, actually; friendly obedience and a relaxed personality found in support animals suggested to be a factor but they never measured that either I guess.
• 95% report greater life consistency and a sense of love, so maybe pets are helpful for someone in vital need of emotional support, we don't know.
Overall, I think if they tried really, really hard, and I mean really put their minds to it, they could write a worse headline for such an ambiguous and unhelpful article.
