Being repeatedly late may just be accidental – or could it show a deeply rooted psychological desire to express your own superiority? When I worked in an office, meetings would often start late, usually because of a certain individual. Then they would overrun and the whole day lost its shape. But the individual was high-ranking and self-important: nobody challenged. So what are the ethics of lateness?
There’s a psychotherapist called Irvin Yalom who argues that all behaviour reflects psychology. Just as people who like to be on time are motivated by certain deep-seated beliefs, so those who make others wait are acting out an inner agenda, often based on an acute sense of power. There’s famous footage in which Silvio Berlusconi kept Angela Merkel waiting while he made a call on his mobile. It speaks volumes.
But that is when all lateness is in one’s control. What about when your train is cancelled or your flight is delayed or you had to wait longer for the plumber to arrive? In such cases, there’s not a lot of psychology involved. Or is there? Some people will genuinely worry about the impact it will have on those left waiting, while others might secretly enjoy the power of their absence.
The essential fact is that lateness means breaking a convention – you can only be late in respect of a time agreed with other people. Regardless of psychology, it has a social value. And when we treat other people’s time as less valuable than our own, we treat them as inferior.
What is the “speak volumes” in paragraph 2 closest in meaning to?

What unusual or unique biological train led to the remarkable diversification and unchallenged success of the ants for over 50 million years? The answer appears to be that they were the first group of predatory eusocial insects that both lived and foraged primarily in the soil and in rotting vegetation on the ground. Eusocial refers to a form of insect society characterized by specialization of tasks and cooperative care of the young; it is rare among insects. Richly organized colonies of the land made possible by eusociality enjoy several key advantages over solitary individuals.
Under most circumstances groups of workers are better able to forage for food and defend the nest, because they can switch from individual to group response and back again swiftly and according to need. When a food object or nest intruder is too large for one individual to handle, nestmates can be quickly assembled by alarm or recruitment signals. Equally important is the fact that the execution of multiple-step tasks is accomplished in a series-parallel sequence. That is, individual ants can specialize in particular steps, moving from one object (such as a larva to be fed) to another (a second larva to be fed). They do not need to carry each task to completion from start to finish - for example, to check the larva first, then collect the food, then feed the larva. Hence, if each link in the chain has many workers in attendance, a sense directed at any particular object is less likely to fail. Moreover, ants specializing in particular labor categories typically constitute a caste specialized by age or body form or both. There has been some documentation of the superiority in performance and net energetic yield of various castes for their modal tasks, although careful experimental studies are still relatively few.
What makes ants unusual in the company of eusocial insects is the fact that they are the only eusocial predators (predators are animals that capture and feed on other animals) occupying the soil and ground litter. The eusocial termites live in the same places as ants and also have wingless workers, but they feed almost exclusively on dead vegetation.
