Confirmation vs. Conformation: What's the Difference?

Edited by Harlon Moss || By Janet White || Updated on October 4, 2023
Confirmation is the act of verifying or validating something, while Conformation refers to the structure, form, or shape of something.

Key Differences

Confirmation is a term that signifies the act of confirming, validating, or asserting the truth or authenticity of something. In contrast, Conformation addresses the structure, form, or arrangement of something, particularly its physical shape.
When you receive Confirmation of a hotel booking, it assures you that your reservation is secured. On the other hand, when someone speaks about the Conformation of a molecule in chemistry, they are discussing its spatial arrangement.
Religious rites, particularly in Christianity, include a sacrament called Confirmation that strengthens a person's faith. Whereas, breeders might discuss the Conformation of a horse, referring to its physical build and bone structure.
Confirmation can also be a psychological phenomenon, such as confirmation bias, where individuals favor information that confirms their pre-existing beliefs. Conformation, in the meantime, can be used in a broader context, like the conformation of a landscape to a particular terrain.
Email systems often send Confirmation emails to ensure a user's action, like subscription or password reset. In the domain of biology, proteins can have different Conformational states, which means they can change their structure under certain conditions.
