Proverbs 2:2, Ecclesiastes 7:25, and 1 Thessalonians 5:21 ("test all things") encourage active critical thinking. Proverbs 3:5 ("lean not on your own understanding") and 2 Corinthians 10:5 ("bringing every thought into captivity to the obedience of Christ") push the opposite direction — distrust your own reasoning and submit your thoughts. The Bible's epistemology argues with itself.

People have answered this in several ways; GEBible presents them as equal peers.

How critical scholarship weighs this: Leans toward reconciliation
This summarizes where critical scholarship tends to land on this tension — a report on the field’s center of gravity, not GEBible’s own ruling.
The contradiction reaches the epistemological foundations of the biblical tradition: how far is the individual mind trusted as an instrument of truth? On the affirmative side stand the wisdom texts. Proverbs 2:2 enjoins inclining the ear to wisdom and applying the heart (lev — the Hebrew organ of cognition, not emotion) to understanding. Ecclesiastes 7:25 has Qohelet describe turning his heart "to know and to search and to seek out wisdom and the reason of things" (heshbon). Qohelet is the most relentlessly first-person reasoner in the Hebrew Bible: the verbs of self-directed investigation — I said in my heart, I gave my heart to seek, I saw, I considered — saturate the book, and Seow's Anchor Bible commentary reads this as a deliberate epistemic stance in which the autonomous investigator reaches conclusions on his own authority, even unwelcome ones. 1 Thessalonians 5:21, panta de dokimazete, "test everything," is straightforward epistemic activism; Malherbe situates it in the assembly's discernment of prophetic utterance, where the community is charged to weigh claims rather than accept them passively. Acts 17:11 commends the Bereans for "examining the scriptures daily to see whether these things were so" — explicitly checking even apostolic preaching.
The negative side is textually narrower than it first appears. Proverbs 3:5 — al-tisha'en el-binatekha, "do not lean on your own understanding" — sits two columns from Proverbs 2:2 in the same composition. Michael Fox argues the proverb does not forbid reasoning but contrasts self-sufficient autonomy with trust in Yahweh; the antithetic parallelism ("trust in the LORD with all your heart" / "do not lean on your own understanding") frames the issue as where one's ultimate confidence rests, not whether one thinks at all. The verb sha'an connotes leaning one's full weight on a support, so the prohibition is against making one's own intellect the load-bearing foundation, not against using it. Likewise 2 Corinthians 10:5 is heavily context-bound: Paul is dismantling specific rhetorical and philosophical arguments raised against his gospel by Corinthian opponents. The "thoughts" he captures are logismoi — calculations, reasonings, polemical arguments — not human cognition as such. Thrall's ICC and Furnish's Anchor Bible volume both read the military metaphor (demolishing strongholds, taking captives) as aimed at the opposition's discourse, not at the believer's faculty of reason.
The harmonization is therefore partly sound and should be granted its due. Read in context, the wisdom texts commend inquiry conducted under the canopy of trust in Yahweh, and the Pauline submission texts target specific oppositional arguments rather than human thinking per se. An honest reader cannot claim Proverbs 3:5 forbids all reasoning, nor that 2 Corinthians 10:5 demands intellectual self-lobotomy.
Yet the harmonization papers over a real divergence in the canon's deeper assumptions. The wisdom tradition assumes the human capacity for inquiry yields reliable knowledge: Qohelet investigates and reaches conclusions on his own authority, sometimes in tension with received orthodoxy, and the canon preserves his dissent. The later New Testament increasingly subordinates reasoning to revelation and apostolic authority. The Pastoral Epistles — held by most critical scholars to be deutero-Pauline, written in Paul's name a generation or more after his death — push hardest in this direction: 1 Timothy 6:3-4 and 2 Timothy 4:3 turn on "sound doctrine" (hygiainousa didaskalia) versus those who "will not endure" it, reframing the intellectual task as adherence to a deposited body of teaching (the parathēkē of 1 Timothy 6:20) rather than open investigation. The trajectory runs from Qohelet's autonomous searching toward institutional gatekeeping of orthodoxy. No single verse forbids thinking, but the canon's center of gravity shifts measurably from inquiry to conformity.
Where the critical reading lands: the surface contradiction is largely harmonizable through context and parallelism, but the underlying trajectory — from wisdom-tradition inquiry to apostolic-authority submission — is real, ideologically significant, and not dissolved by the contextual readings.
