Business Rules are executed when the form/flow loads and when a control's value that the rule depends on changes. If you want your rule to run Only when the form loads - check the Initialization Only checkbox at the top of the wizard. You may want some business logic to execute before the form/flow displays and users begin interacting with it.

(need good example) - 

When the rule displays in the Rule Builder tab, it will indicate that the rule has been flagged to run only when the form loads, if this checkbox is checked.
