When people sing together in a choir for 20 minutes, their body’s oxytocin levels drop—unlike when they sing alone, where levels stay the same. This surprises scientists because they thought group activities like this always boost oxytocin, the ‘bonding hormone.’
Claim Language
Language Strength
association
Uses association language (linked to, correlated with)
The claim uses 'is associated with' and 'shows no significant change,' which indicate statistical correlation rather than causation. The phrase 'challenging the assumption' further reinforces a correlational tone by implying an observation that contradicts a general belief without asserting direct causation.

Choir versus Solo Singing: Effects on Mood, and Salivary Oxytocin and Cortisol Concentrations
The study found that singing in a choir made people’s oxytocin levels go down, not up, while singing alone didn’t change anything — which means being social doesn’t always boost this 'bonding' hormone like people thought.
