The twelve men sent by Moses to explore the land of Israel returned with a report that was not merely pessimistic, but fundamentally misleading. They claimed:
“We cannot go up against those people, for they are stronger than us . . . The land which we have journeyed through and scouted is a land that consumes its inhabitants; and all the people we saw were tall and broad to a man.” (Num. 13:31-32)
History, however, tells a different story. As we discover later in the Book of Joshua, the inhabitants of Canaan were actually terrified of the Israelites. Rahab told Joshua’s spies: “A great fear of you has fallen on us... our hearts melted in fear and everyone’s courage failed because of you” (Josh. 2:9-11).
The spies should have anticipated this. They had already sung at the Red Sea: “The people of Canaan melted away; terror and dread fell upon them” (Ex. 15:15-16). Why, then, did they see giants where there were only trembling hearts?
The Trap of Social Projection
The spies were guilty of what psychologists call Social Projection—the cognitive bias where we attribute our own Dean, beliefs, and fears onto others. They famously said: “We were like grasshoppers in our own eyes, and so we were in their eyes” (Num. 13:33).
As the Kotzker Rebbe perceptively noted, they were entitled to the first claim, but not the second. They knew how they felt, but they had no way of knowing what the Canaanites saw. In psychology, this is often linked to the Spotlight Effect. As Thomas Gilovich notes, “We tend to believe that others are paying more attention to our flaws and anxieties than they actually are.” Because the spies felt small, they assumed the world viewed them as microscopic.
Fixed vs. Growth Mindsets
Why did ten spies fall into this trap, while Joshua and Caleb remained immune? To understand this, we can turn to the work of Stanford psychologist Carol Dweck. In her seminal work, Mindset, Dweck explores why some people fulfill their potential while others plateau.
Her research centers on two distinct frameworks. Those with a Fixed Mindset believe their abilities are innate and unalterable. For them, every challenge is a test of their "natural" worth. If they fail, it is not just a mistake; it is a definition of who they are. Conversely, those with a Growth Mindset believe that talent is merely a starting point. They view effort as the path to mastery and failure as "information"—a necessary step in the learning process.
Dweck writes:
“In a fixed mindset, challenges are a threat because they might reveal you are not as talented as you think. But in a growth mindset, the hand you’re dealt is just the starting point for development.”
Those with a fixed mindset play it safe. They avoid risks because their self-image is fragile. As Dweck observes, they thrive only “when things are safely within their grasp. If things get too challenging... they lose interest.”
The Burden of Status
The Torah identifies the spies as “leading men among the Israelites” (Num. 13:3). They were princes, men of renown with reputations to protect. In psychological terms, they were susceptible to Loss Aversion—the phenomenon where the pain of losing status is far more powerful than the motivation to gain something new.
Because they were "great men," they had everything to lose. If they attempted to conquer the land and failed, their legacy would be tarnished. A fixed mindset, coupled with high status, often results in a paralyzing fear of failure. They chose the safety of the desert over the risk of the Land because, to a fixed mindset, "not trying" is a safer defense for the ego than "trying and failing."
The Anatomy of Courage
Joshua and Caleb were the exceptions. Caleb descended from Judah, the first true ba’al teshuvah (penitent). Judah’s life was defined by a growth mindset; he transformed from the man who suggested selling Joseph into the man who offered his own life to save Benjamin. He proved that a human being is not a fixed entity, but a work in progress.
Joshua’s transformation was literally etched into his name. Moses changed his name from Hoshea to Yehoshua (Num. 13:16). In Jewish thought, a name change signifies a change in essence. As Maimonides writes, it is a way of saying, “I am another person and not the same one who did those deeds” (Mishneh Torah, Laws of Repentance 2:4).
Joshua and Caleb possessed what Albert Bandura called Self-Efficacy: the belief in one’s ability to execute the behaviors necessary to produce specific performance attainments. Bandura noted:
“In order to succeed, people need a sense of self-efficacy, to struggle together with resilience to meet the inevitable obstacles and inequities of life.”
The Paradox of Success
The ten spies failed because they were afraid to fail. They were so concerned with their image—as leaders and as "grasshoppers"—that they lost sight of the God who had split the sea. Joshua and Caleb, however, knew that the struggle was the point.
The message of the spies is a foundational principle of psychological resilience: God does not demand perfection; He demands the courage to move forward. He provides the "growth" as long as we provide the "mindset."
Ultimately, we are faced with a liberating, if paradoxical, truth: The fear of failure is the greatest predictor of failure. It is only the willingness to fail—to be a "grasshopper" that keeps on jumping—that allows us to eventually conquer the land.
