Too true Steve!
To your point there are means that don't involve first thrusting ourselves in something before using a type of tool to aid us in our discernment!

;DHehehe
Yea with some people and with nature sometimes the first risk we take can be the fatal one.
Discernment is the ability to properly discriminate or make determinations. It is related to wisdom. The Word of God itself is said to discern the thoughts and intentions of one’s heart (Hebrews 4:12). A discerning mind demonstrates wisdom and insight that go beyond what is seen and heard.
...God is alive and active. Sharper than any double-edged sword, it penetrates even to dividing soul and spirit, joints and marrow; it judges the thoughts and attitudes of the heart.
