The Pike Effect in Sales

When Sales Teams Stop Fighting for Deals

In behavioral psychology, there is a fascinating experiment often referred to as the Pike Effect.

A predatory pike fish was placed in a tank with smaller fish it would normally hunt. Between them was a transparent glass barrier. Each time the pike attempted to attack, it hit the invisible wall.

After several painful attempts, the pike stopped trying.

Eventually, the glass barrier was removed. The smaller fish swam freely in front of the pike, exactly where the predator could easily reach them.

But the pike never attacked again.

It had learned that trying was pointless.

Even when the obstacle disappeared, the behavior remained.

Surprisingly, something very similar happens inside many sales teams.

How the Pike Effect Shows Up in Sales

Sales professionals rarely start their careers with hesitation. Most begin with enthusiasm, curiosity, and a strong desire to win.

But repeated experiences can slowly reshape behavior.

A salesperson pursues a large enterprise deal for six months. Multiple meetings, demonstrations, technical discussions, and proposal revisions. At the final stage, the client suddenly chooses a competitor who offered a steep discount.

Another opportunity progresses well until procurement enters the conversation and squeezes the margins to a level where the deal no longer makes commercial sense.

A third deal looks promising but disappears after the client repeatedly postpones decisions.

None of these events are unusual in sales. But when they occur repeatedly, something subtle begins to change.

Salespeople start protecting themselves from disappointment.

They begin avoiding the deals that once excited them.

A Real Pattern I Often Observe

I once worked with a sales team where the leadership believed their pipeline was shrinking because the market had become more competitive.

But when we studied their behavior more closely, a different pattern emerged.

The team had stopped pursuing large strategic opportunities.

Instead, they were focusing on smaller, easier deals that required less effort and carried fewer risks of rejection.

When asked why they were not engaging with larger prospects, the responses were telling:

“Those companies already have preferred vendors.” “They will eventually push for heavy discounts.” “It takes too long to close those deals.”

In reality, the market had not changed dramatically.

What had changed was the team’s belief about their chances of success.

Like the pike fish in the experiment, they had encountered the invisible barrier too many times.

So they stopped trying.

The Silent Risk for Sales Leaders

The Pike Effect is dangerous because it rarely announces itself.

Salespeople still attend meetings. They still update the CRM. They still report activity.

But the intensity to pursue meaningful opportunities quietly fades.

Over time, this leads to smaller pipelines, slower growth, and reduced confidence across the team.

The barrier may no longer exist.

But the behavior continues.

Breaking the Pike Effect

Reversing this pattern requires more than asking salespeople to “try harder.”

It requires rebuilding belief.

Sales leaders must help teams experience progress again by encouraging them to pursue meaningful opportunities, supporting them through complex deals, and removing internal barriers that repeatedly block progress.

Sometimes all it takes is a few genuine wins to restore the instinct to compete.

Because deep down, most sales professionals still have that hunger.

It simply needs to be reawakened.

In My View

After many years of working with sales teams, I have realized that the greatest barriers in sales are rarely external. Often they exist in the mind. When people repeatedly encounter obstacles, they begin to adjust their expectations of what is possible. And once that happens, the biggest risk is not losing deals. It is losing the courage to pursue them.

Sometimes the most important role of a sales leader is simply this:

To remind the team that the glass barrier may no longer be there.
