Understanding personal finance advice is more important than ever. Many popular financial tips have become mainstream, but how well do they align with what top academics recommend? This article dives into five scientifically-backed tips for personal finance management, based on the work of James J. Choi, Professor of Finance at Yale School of Management. Drawing from his comprehensive study “Popular Personal Financial Advice versus the Professors,” we’ll uncover what the research really says about personal finance for beginners and experienced investors alike.
Who Is James J. Choi?
James J. Choi is a Professor of Finance at the Yale School of Management, with deep expertise in behavioral finance and household finance—the science of how people and families make everyday financial decisions. Choi’s groundbreaking work on automatic enrollment in retirement plans has shaped pension design worldwide. He is a two-time recipient of the TIAA Paul A. Samuelson Award for his outstanding writing on lifetime financial security. Choi also serves as Associate Editor of the Journal of Finance, co-director of the Retirement and Disability Research Center at NBER, and has held influential committee roles at FINRA and the American Finance Association. His academic credentials include a Ph.D. in Economics and an Applied Mathematics background from Harvard University.
What Makes Good Personal Finance Advice?
Many personal finance books offer rules of thumb—simple tips for saving, spending, and investing. But not all advice is grounded in research. As Choi points out, “Many personal finance rules of thumb are not evidence-based” (Choi, 2022). Let’s separate myth from reality with these five evidence-backed strategies.
1. Pay Yourself First
One of the most frequently cited pieces of personal finance advice is to “pay yourself first.” This means that as soon as you receive your income, you automatically set aside a specific portion in a separate account—preferably one that is harder to access. As David Bach famously said, “The secret… is that you can’t spend what you don’t see.” The idea is that whatever remains after this automatic saving can be spent more freely, without the pressure of strict budgeting.
Why does it work?
Automating your savings uses your own psychology to your advantage. If you never see the money in your checking account, you’re much less likely to spend it impulsively. This is a key principle taught in many personal finance courses and is especially useful for beginners learning to build wealth.

2. Prioritize Building Emergency Savings
Research shows that 28 popular personal finance books emphasize the need for an emergency fund—an accessible stash of money set aside for unexpected expenses. This approach protects you from becoming a “wealthy hand-to-mouth” household, a term coined by Kaplan, Violante, and Weidner (2014).
What is a wealthy hand-to-mouth household?
These are families who have assets tied up in their home or retirement accounts but little cash on hand. According to the study, about 20% of U.S. households fall into this category. Their portfolio makes sense only if those illiquid assets yield very high returns. Otherwise, not having liquid savings leaves them vulnerable to income shocks.
Why is this important?
If your money is locked away in assets you can’t easily access, you may struggle to cover emergencies without going into debt. This underscores the importance of personal finance basics—like keeping at least three to six months’ expenses in an emergency fund.
3. Contribute Enough to Get the Maximum 401(k) Match
Saving for retirement is essential, and many employers offer a matching contribution to your 401(k) plan. The best advice: always contribute enough to get the full match. This is essentially free money, and passing it up is leaving part of your compensation on the table.
But what about emergency savings versus retirement savings?
Some books recommend putting retirement savings ahead of building an emergency fund. However, research suggests it’s generally smarter to secure a cash buffer before locking money away for decades. Find the right balance for your situation, but don’t miss out on matching contributions—they’re one of the simplest ways to build wealth for the future.
4. A House Is Not Always a Great Investment
Buying a home is often seen as the cornerstone of the American dream, but is it always a wise financial move? Fourteen financial guides reviewed by Choi say a house is not a great investment. While homeownership has its benefits, it also ties up a lot of money in a single, illiquid asset.
Why be cautious?
Houses come with ongoing costs: maintenance, taxes, insurance, and sometimes, market risks. Plus, if you put all your money into your home and neglect emergency savings, you may find yourself asset-rich but cash-poor. As the research shows, it’s crucial to avoid becoming a “wealthy hand-to-mouth” household just to afford a bigger house.
5. Spending in Retirement: There’s No One-Size-Fits-All
Advice on how much you’ll spend in retirement varies widely. Some experts say you should expect to spend less after leaving the workforce, while others recommend keeping your spending steady. Fifteen books surveyed by Choi cover this topic, but no consensus exists.
What’s the takeaway?
Plan your retirement spending based on your own lifestyle, health, and goals—not on a generic rule of thumb. Track your current expenses and make realistic projections. A personal finance course or advisor can help tailor a plan that works for your unique needs.

Wealthy Hand-to-Mouth: The Portfolio Trap
Kaplan, Violante, and Weidner (2014) found that about one in five U.S. households are “wealthy hand-to-mouth”—they own substantial assets, but almost no cash. This portfolio mix might be justified if illiquid assets (like real estate or retirement accounts) offer extremely high returns, but this is rarely the case in practice.
Illiquidity as Self-Control
Research by Angeletos et al. (2001) interprets the preference for illiquid assets as a self-control strategy. By locking money away in assets that are hard to spend, individuals protect themselves from the temptation of overspending.
