Researchers from the University of Hohenheim analyze the budget debate in the Bundestag - and find out.
Some of the speeches are incomprehensible.
Berlin – When the twentieth Bundestag met for the first time in October 2021, the boss made a clear statement.
"Politics is only good if it is understandable," said President Bärbel Bas (SPD) in her inaugural speech.
Only those who speak clearly can reach those who no longer feel addressed by "politics".
"We can use our language to show that we have the best interests of everyone in mind," said Bas.
She received applause from all ranks for her words.
But there is a lack of comprehensibility in the Bundestag, as a study by the University of Hohenheim shows.
On the whole, the researchers are satisfied with the speeches.
For example, they are more understandable than those of the Dax board members at their general meetings, as co-author Frank Brettschneider says.
"Nevertheless, some have room for improvement."
Linke delivers the best speech: Lauterbach and Lambrecht are also up front
For their study, Brettschneider and his team took 96 speeches from last September's budget debate and checked them for comprehensibility.
"Foreign words and technical terms, compound words and nominalizations, Anglicisms and 'Denglisch', long sentences - all of this makes it difficult to understand," says co-author Claudia Thoms.
From such criteria, Brettschneider and his team developed the comprehensibility index, which is intended to make the results comparable.
Their results show that some politicians are already close to the optimum with their speeches, but the scatter is large.
The left-wing politician Gesine Lötzsch gave the most understandable speech according to the index criteria with 19.5 out of 20 possible points.
From the cabinet, the then Defense Minister Christine Lambrecht (SPD), Education Minister Bettina Stark-Watzinger (FDP) and Health Minister Karl Lauterbach (SPD) did best.
The speech by the CDU politician Kerstin Vieregge achieved the fewest points with 7.9.
For comparison: doctoral theses in political science average 4.3 points.

Criticism of speeches in the Bundestag: More and more "Denglisch"
There is one trend that the team complains about: more and more "Denglisch", i.e. the mixing of German and English.
There is talk of "game changer instruments" or "out-of-the-box thinking".
English is seeping deeper and deeper into German, as the new additions to the dictionary show.
Such anglicisms could serve in the political debate to give himself and his party a modern look, said Marcus Maurer, professor of political communication at the University of Mainz.
There are certainly terms that politicians should avoid.
However, comprehensibility down to the last word is not the primary goal.
“Studies show that the climate is getting rougher in Parliament”
"The speeches are aimed at the public, but the media are in between," said Maurer.
In their reporting they would have to penetrate with their speeches.
"And the MPs have experience with what you have to say to appear in the daily topics in the evening," said Maurer.
Emotionalizing or attacking political opponents are tried and tested methods.
"Studies show that the climate is getting rougher in Parliament."
According to Brettschneider's team, one of the most common violations of the rules of comprehensibility is “beasts of the word”: long, compound words that people like to use for laws.
The "Bundeswehr Procurement Acceleration Act" or the "SprinD Freedom Act" are given as examples.
