unacknowledged

To me there seems to be a mismatch, an unacknowledged element to the definition, which is that it has to counter some official narratives.

When people died, the use of sedation often went unacknowledged publicly and unquestioned by investigators.

The aftershocks — often unacknowledged in the years before mental health struggles were more widely recognized — led to some survivors suffering insomnia, dropping out of school, or disengaging from their spouses or families.

Mankiewicz’s work often went unacknowledged, but he’d helped give the 1930s comedies the rat-a-tat rhythm of he and his friends ping-ponging jokes around the Algonquin Round Table.

"For too long the courage you showed has been unacknowledged. For this, we offer both our deepest apologies and our sincere admiration."
