Availability Bias #2: Why Some Languages Become Less Accessible

Introduction

There are some cognitive biases we understand intellectually, and others we recognize very personally. For me, the availability bias is one of those.

Over time, I noticed that my relationship with German had gradually weakened as my English became more fluent, more spontaneous, and easier to access. It’s not that German disappeared. But it became less immediately available, less present in my automatic responses, and less easy to retrieve when I needed it.

I also see something similar when I go to Spain. Even though I understand Spanish and would love to practice it more, my exchanges usually remain very short. With my Italian-speaking colleagues, I naturally switch to Italian more often, because that language comes to me faster and feels more effortless. As a result, my Spanish rarely goes beyond a simple sentence.

This is fascinating, because it shows how much our brains prefer what requires the least effort. The language that is most present, most frequently activated, or most recently used becomes the most accessible. The others are still there, but they move a bit further into the background.

When One Language Takes the Lead

In multilingual life, it is common for one language to become dominant. That does not necessarily mean the other languages are lost. More often, they simply become less accessible.

This is where the availability bias connects with multilingual experience. What comes to mind first is not always what is most useful or most precise. It is often what has been used most often, practiced most recently, or emotionally reinforced the most.

When a language becomes dominant, it tends to shape how quickly we retrieve words, expressions, and structures. Another language may still be well known, but it takes longer to reach. In daily life, that difference can feel like fluency in one language and frustration in another.

Is It Loss or Reduced Access?

It is important to distinguish between losing a language and simply losing easy access to it.

Research on language attrition suggests that what people often experience is not a total disappearance of knowledge, but a drop in accessibility, automaticity, or fluency. A language may still exist in memory, but the path to it becomes less direct.

That distinction matters, because it changes the emotional meaning of the experience. If a language feels harder to use, it does not automatically mean that ability is gone. It may simply mean that the language has not been activated often enough.

Why This Happens

Several factors influence why one language becomes more accessible than another:

• frequency of use,

• dominance in daily life,

• similarity between languages,

• emotional context,

• lexical retrieval speed,

• and how often a language is actively practiced.

When two languages are close, interference can become more noticeable. Spanish and Italian, for example, can easily overlap in the mind because they share similar vocabulary, rhythm, and structure. The brain then has to choose, inhibit, and sort more actively. That extra effort can make one language feel harder to access, even when it is still very much there.

What It Feels Like in Real Life

This is where the experience becomes very human.

You may know a language, understand it well, and even feel fond of it, but still find yourself reaching for another language first. That can be surprising, and sometimes frustrating. It may even create the feeling that you are “losing” something.

In reality, what is often happening is simpler and more nuanced: your brain is following the shortest path. It goes first toward the language that is currently most available.

For me, that has meant noticing how German became less immediate as English became more fluent. It has also meant realizing that, in Spain, Italian often arrives before Spanish. Not because Spanish is absent, but because Italian is more readily activated in the moment.

How to Reactivate a Less Accessible Language

The encouraging part is that a less accessible language can become more available again.

You do not need to start over. You need to re-create access.

A few helpful strategies include:

• reading short texts regularly,

• listening to simple content,

• writing a few sentences each week,

• reviewing useful vocabulary,

• speaking in small, safe doses,

• and creating short routines of reactivation.

The goal is not perfection. The goal is to rebuild pathways so the language can come back more quickly when needed.

What This Bias Teaches Us

The availability bias reminds us that what comes first to mind is not always what matters most. In multilingual life, this can explain why one language seems to take over while another becomes quieter.

But quieter does not mean gone.

It often means:

• less activated,

• less practiced,

• less immediately reachable,

• or simply less supported by recent use.

That shift is important, because it replaces guilt with understanding. It also creates room for action.

Conclusion

When one language takes up more space than another, it is not always a question of loss. Often, it is a question of access.

A language can become less available without disappearing. And if it can become less available, it can also become available again.

For multilingual speakers, that is a reassuring thought: languages are not fixed objects. They are living systems, shaped by use, context, frequency, and relationship.

It’s not always a language we lose. Sometimes, it’s simply a language we reach less quickly.
