Have you ever tried to read a book while someone next to you is having a loud conversation on the phone?
2+
You probably found yourself reading the same sentence three times without understanding a word.
3+
4+
This isn't because you aren't focused; it is because of a psychological glitch called the **Irrelevant Speech Effect (ISE)**.
5+
6+
Here is the simple breakdown of why this happens and why your favorite playlist might be killing your productivity.
7+
8+
## What is the "Irrelevant Speech Effect"?
9+
10+
Imagine your brain’s working memory is like a **single-lane bridge**. This bridge is responsible for processing language—whether that's reading an email, writing code, or studying for an exam.
11+
12+
When you are working, you are sending "cars" (words and thoughts) over this bridge.
13+
- Silence: The cars move smoothy.
14+
- Instrumental Music: A little scenery on the side of the road, but the traffic flows.
15+
- Speech (or Lyrics): This is like a massive truck trying to force its way onto that same single-lane bridge from the opposite direction.
16+
17+
Even if you _try_ to ignore the speech, you can't. Your brain is hardwired to prioritize human voices.
18+
It involuntarily tries to process the words it hears, causing a traffic jam on the bridge. This crash is the Irrelevant Speech Effect.
19+
Why You Shouldn't Listen to Lyrical Music While Working
20+
21+
You might think, **"I'm not listening to the lyrics, I'm just vibing."** Unfortunately, your subconscious disagrees.
22+
23+
If your task involves words (reading, writing, coding, planning), your brain uses a system called the **Phonological Loop.**
24+
This is the inner voice you hear when you read silently.
25+
26+
When you play music with lyrics:
27+
28+
- Conflict: Your inner voice (reading/thinking) starts fighting with the singer's voice.
29+
- Processing Power: Your brain wastes energy trying to filter out the singer's words to focus on your own thoughts.
30+
- Result: Your IQ temporarily drops, you make more mistakes, and you get tired faster.
31+
32+
### Real-Life Examples
33+
34+
- The Coffee Shop Dilemma: You can work fine in a coffee shop with the hum of a machine or clinking cups (white noise). But the moment the couple at the next table starts arguing about their relationship, your focus shatters.-
35+
- The Open Office: You are trying to write an important email, but a colleague two desks away is explaining a recipe. Suddenly, you find yourself typing "pasta" into your professional report.-
36+
- TV in the Background: You think having the news on helps you relax while studying, but you realize you’ve been staring at the same page for 20 minutes because your brain is tracking the reporter's voice.
37+
38+
### The Solution?
39+
40+
If you are doing manual labor (like washing **dishes**), lyrical music is great! **It keeps you energized.**
41+
42+
But for deep mental work:
43+
44+
- Stick to Lo-Fi beats, Classical, or Video Game Soundtracks.
45+
- These genres have no words, so they occupy the "emotional" part of your brain without crashing into the "language" bridge.
