That distortion and change in perspective also affects how a viewer will perceive the face of someone that you are taking an image of. This is true for selfies and it is true for regular portraits.

Since this subtler distortion is not obvious, your mind just buys the image thinking that this is what the person looks like. The same happens with larger focal lengths.

Compare the image taken with the 24mm lens with the 80mm image below it showing the tower at the same height using different focal lengths. You can see the degree to which the verticals have been ...

That's because different focal lengths (offering different fields of view) result in unique views of a scene, allowing you to create dramatically different images based on which lens you select.
