Conflicting interests may result in misleading claims about the effect of interventions. Someone with an interest in getting people to use an intervention, such as making money, may overstate benefits and ignore possible negative effects.
People urging others to use a intervention may just want to help. But they also may have other reasons, for example to make money. This can lead them to exaggerate how good the intervention is and to ignore how harmful it may be.
Similarly, people urging others not to use a intervention may have different reasons for doing this (for example moral beliefs).
BEWARE of claims about the effects of interventions that are made by people who make money from selling the intervention or who have other, possibly conflicting, interests besides supporting farmers.
REMEMBER: Think about whether someone making a claim about the effects of an intervention may have a vested interest in it. If they do, be careful not to be fooled by their claim.
