A common claim suggests that friends who roast each other tend to be more honest and loyal, and while the exact statistics behind that idea are often unverified, research on social behaviour and humour does support the underlying pattern.
Studies and commentary on friendship dynamics show that playful teasing—often referred to as “pro-social teasing”—is closely linked to trust and emotional closeness. Psychologists describe it as a form of interaction where the structure resembles an insult, but the intent is positive and relationship-building.
One reason this works is because teasing signals familiarity. When friends joke about each other’s habits or quirks, they are demonstrating a level of understanding that typically only comes with a close relationship. In that sense, roasting acts as a form of social shorthand—it shows that both people are comfortable enough to drop formalities and interact more openly.
There is also a connection to honesty. Researchers note that teasing can function as a softer way of delivering feedback. Instead of directly criticizing a behaviour, friends often frame it as humour, which lowers the risk of conflict while still communicating something real. This allows for more candid interactions without damaging the relationship.
At a group level, teasing can help regulate social dynamics. Psychologists have found that light, mutual insults can keep egos in check and reinforce equality within a friendship or group. This kind of interaction helps maintain balance, which is an important factor in long-term relationship stability.
However, the research consistently highlights that the effect depends on context. Teasing is only associated with stronger relationships when it is mutual, clearly understood as playful, and based on an existing level of trust. When those conditions are missing, the same behaviour can be interpreted as criticism or aggression rather than bonding.
Overall, while exaggerated statistics often circulate online, the broader conclusion is supported by research: playful roasting, when done within a healthy dynamic, can reinforce trust, encourage honest communication, and strengthen long-term friendships.
