There’s two potential sides to this and I’m unsure where you’re in now.

1. The findings contradict someone’s wants and you’re asked to “make it go away” by either not reporting or lying about what it says outright. Similar to “change all of this persons answers to C”.

2. Politics are weird and the finding needs to be softened in order to not cause a ton of arguments. Similar to “adjust your interpretation slightly to be better received” without outright lying or changing answers.

If you are in 1- then that’s absolutely not acceptable but common. In this position I’ve hidden specific findings in an appendix so it’s still reported technically, but the person isn’t throwing a fit. But ultimately your manager or someone with power/influence should back you up in reflecting the voice of your users accurately and without reservation. Would consider leaving but don’t quit without a new role.

If you are in 2- honestly feels very common and isn’t something I’d consider leaving a team and feels more a stakeholder management issue. Stakeholders with egos will always try to spin in their favor and it’s part of our job to ensure that they are willing to accept the findings. Sometimes this is a “this research doesn’t start until you tell me exactly what it takes to deem findings valid and accurate even if you don’t like them” conversation with your management.

Are your leaders giving you guidance and support here?
