How to Do a Thorough AA 4th Step Inventory (The Complete Guide)

Step 4 stops more people in AA than any other step. Not because it's impossible — millions of people have done it — but because most newcomers sit down with a blank page, a vague memory of "resentments and fears," and zero structure. They write for an hour, get overwhelmed, put the notebook away, and never pick it back up. Then they carry guilt about not finishing Step 4 on top of everything else they were trying to inventory in the first place. This guide fixes that. We'll walk through exactly what the Big Book asks for in Step 4, the exact columns Bill W. specified, common mistakes that derail the process, and the tools (both physical and digital) that make a thorough inventory actually finishable.

What the Big Book Actually Says About Step 4

The Big Book dedicates most of Chapter 5 ("How It Works") to Step 4 instructions. Most people skim this section and remember the phrase "searching and fearless moral inventory" without noticing that Bill W. gave an extremely specific structure for how to do it. He said: make three columns. Column 1: the person, institution, or principle you resent. Column 2: what they did that caused the resentment — the cause. Column 3: which part of you was affected — your self-esteem, pocketbook, ambitions, personal relations, sex relations, or your pride. Then he said to ask yourself three questions for each resentment: Where was I selfish? Where was I dishonest? Where was I self-seeking and frightened? That's the whole structure. Not vague soul-searching. A three-column inventory followed by three specific questions. The people who finish Step 4 are the ones who follow this structure. The people who don't finish are the ones who try to freelance it.

The Four Inventories the Big Book Asks For

Most people only remember the resentment inventory. But the Big Book actually asks for four separate inventories. The Resentment Inventory: who and what you resent, why, and which part of you was affected. The Fear Inventory: every fear you have, why you have it, and whether you're relying on self-reliance (which isn't working) or on something greater than yourself. The Sex Inventory: who you've harmed sexually, what was selfish or dishonest about your behavior, and what a sane and sound ideal for your sexual conduct would look like. The Harms Inventory: people you've harmed in ways not covered by the first three (financially, by neglect, by broken trust, by things you failed to do). Doing all four takes time — usually several weeks of focused work — but skipping any of them leaves gaps that show up later in sobriety. Most people who slip in year 2 or year 3 can trace it back to something they never wrote down in year 1.

Common Mistakes That Derail Step 4

Mistake 1: Trying to do Step 4 without a sponsor. The Big Book assumes you have a sponsor guiding you through the process. Without one, it's easy to go off the rails, get stuck on one resentment for days, or skip difficult items. Mistake 2: Trying to do it from memory without a structured template. You'll miss things. Your brain is protective — it hides the worst items until they're forced to the surface. A structured template catches what memory misses. Mistake 3: Making it too short. A thorough 4th Step usually covers 50-200 resentments, dozens of fears, and years of sexual and financial harms. If your inventory fits on three pages, you're not done. Mistake 4: Making it too long. On the other side, some people get stuck journaling their feelings instead of inventorying their behavior. Step 4 is an inventory, not a diary. Stick to facts and columns. Mistake 5: Waiting to start until you "feel ready." You'll never feel ready. Ready is a feeling that comes after starting, not before.

The Right Tools for a Thorough 4th Step

Step 4 is a paper-and-pen step. There's something about the physical act of writing by hand that bypasses the rationalizing parts of the brain. Typing on a laptop is too easy to edit in real time — you end up writing what you wish were true instead of what actually is. A physical inventory packet forces honesty because you can't delete what you've written without literally scribbling it out. This is why many sponsors recommend the 4th Step Packet from AAmazingtabs — it gives you the exact column structure Bill W. specified, pre-formatted pages for each of the four inventories, and enough room to actually complete a thorough inventory without running out of space. The packet does the structural work so you can focus on the honesty work. For the reading portion of Step 4 (Chapter 5 of the Big Book), pairing the packet with a tabbed and highlighted Big Book lets you flip directly to the instructions whenever you need to reference them — which, in our experience, is often.

How AABluebook Supports Your 4th Step Work

The physical 4th Step Packet is for the structured inventory itself. But there are three ways AABluebook supports the process in parallel. First, the Interactive Big Book with the 1930s dictionary helps you understand what words like "moral," "inventory," "selfish," and "self-seeking" actually meant to Bill W. in 1939 — which changes how you interpret the questions you're asking yourself. Second, the Digital God Box is where many members place the inventory items they finish each session — it creates a ritual of surrender at the end of each writing block, so you don't carry the weight of what you just wrote into the rest of your day. Third, the AI Recovery Coach is available 24/7 for the hard moments during 4th Step work when something surfaces that feels too big to sit with alone and your sponsor isn't picking up. The coach isn't a replacement for a sponsor, but it's a bridge for the 3 AM moments. You can download AABluebook for a free 7-day trial — no credit card required.

A Realistic Step 4 Schedule

Most people who try to do Step 4 in one sitting burn out and quit. A realistic schedule looks more like this: Week 1, read Chapter 5 of the Big Book slowly, twice. Understand the instructions before you write a single word. Week 2, brainstorm your resentment list — just names and short descriptions. Don't worry about the columns yet. Week 3-4, work through the three-column format for each resentment. 30-60 minutes a day, 4-5 days a week. Some days you'll write 10 items. Some days you'll write one. Both are fine. Week 5, fear inventory. Week 6, sex and harms inventories. Week 7, review the whole thing with your sponsor. This schedule is flexible — some people finish in a month, others take three months. The timeline matters less than the thoroughness. A rushed 4th Step creates more problems than a slow one.

What to Do After You Finish Step 4

Step 4 is not the end — it's the setup for Step 5, which is sharing the inventory with your sponsor, with yourself, and with a Higher Power. Do not skip Step 5. The inventory sitting in a drawer does nothing. The inventory shared out loud with another human being does something almost miraculous: it stops being a secret. Bill W. wrote that "we were as sick as our secrets," and reading a 4th Step inventory to a sponsor is the most reliable way to stop being sick. After Step 5, you move into Steps 6 and 7, where you become willing to have these defects of character removed and ask for their removal. The 4th Step Packet from AAmazingtabs includes guidance for Steps 4 through 9 — because the Big Book treats them as an integrated sequence, not separate tasks.

The Hardest Part Is Starting

If you've been putting off Step 4 for weeks, months, or years — you're not alone, and you're not broken. Step 4 is supposed to be hard. It's supposed to feel intimidating. But "hard and intimidating" is different from "impossible." With the right structure (the Big Book's three columns), the right tools (a physical inventory packet, a tabbed Big Book, and a supporting digital app), and the right pacing (a little each day, with breaks to surrender what comes up), a thorough 4th Step is completely doable. Most people finish and are shocked that it wasn't as devastating as they feared. In fact, most people describe finishing Step 4 as one of the single most freeing experiences of their lives. The weight of carrying unexamined resentments for decades is heavier than the work of writing them down.

Ready to Start Your 4th Step?

If you're ready to finally do the work, here's the setup we recommend: a physical 4th Step Packet from AAmazingtabs for the inventory itself (it has the exact columns Bill W. specified), a tabbed and highlighted Big Book so you can flip directly to Chapter 5 whenever you need to re-read instructions, and AABluebook on your phone for the 1930s dictionary, Digital God Box for end-of-session surrender, and AI Recovery Coach for the hard moments. Then find a sponsor, read Chapter 5 twice, and start writing. One resentment at a time. One page at a time. The weight you've been carrying is about to get lighter.
