The focus of an interest group is to promote a specific cause or issue.
What is focus?
A focus, also known as an image point in geometrical optics, is where light rays originating from one point on the object converge. Despite being a point conceptually, the focus actually has a spatial extent known as the blur circle. The imaging optics' aberrations could be to blame for this suboptimal focusing. The Airy disc, which is brought on by diffraction from of the optical system's aperture, is the smallest blur circle that can be created in the absence of significant aberrations. The Airy circle seems to be smallest for large apertures, while aberrations tend to get worse as the aperture diameter rises. If light from object points has been converged almost to the maximum extent in the image, then the image, or image point or region, is in focus. If light is not well converged, then the image is out of focus.

I don't think parents, should lie to their children, as for children shouldn't lie to their parents. I personally think it is all equal. But if a parent is specifically lying to their children about problems that don't really relay on them, then maybe it's okay. But if it includes divorce, or death's I think that it is not okay for parent's to lie to their children, unless protecting them, from something.
I think it’s Behavioral science
