erred on the side of caution

Played it safe

Erred on the side of caution means chose the safer or more conservative option when facing uncertainty.

The phrase acknowledges that the choice might be unnecessary—an "error"—but accepts that risk as preferable to the alternative: We erred on the side of caution and canceled the outdoor wedding.

The logic is that if you must be wrong, be wrong in the direction that causes less harm.
