Reasons for A Default Selection Give people control and align with their expectations (Good): It is better to have a selected radio button by default, given that people cannot deselect and set the button back to its original state once one has been selected. A default selection sets the correct user expectation.

For most controls you may un-choose a selection you make. (Required elements may catch you with a note or error message later.) But you cannot click or tap a selected radio button to deselect it. The finality of the action of selecting is not conveyed when none are selected by default.

You can check a radio button by default by adding the checked HTML attribute to the <input> element. You can disable a radio button by adding the disabled HTML attribute to both the <label> and the <input> .

In a checkbox group, a user can select more than one option. Each checkbox operates individually, so a user can toggle each response "on" and "off." Radio buttons, however, operate as a group and provide mutually exclusive selection values. A user can select only one option in a radio button group.
